Parabar 10312 (previously known as Paratone)
Applications
- Oil based cryoprotectant
Features
- Synonyms used in the crystallographic literature: Paratone® N, Paratone® 8277, Infineum V8512
- Oil based cryoprotectant
Description
Sorry, Parabar 10312 is no longer available. We’ve left this page up for reference only. See HR2-861 Santovac Cryo Oil as a possible substitute.
Parabar 10312 is a viscous cryoprotectant for both small and large molecule crystallography.1
Mildly air-unstable, small molecule compounds can be coated with Parabar under an inert atmosphere. The Parabar protected crystal sample can be cryocooled in a chilled nitrogen gas stream. Parabar has also been used successfully as a cryoprotectant for biological macromolecule crystals. Used during cryocrystallography to displace and reduce the amount of water (mother liquor, reagent) on the crystal after the crystal is mounted in a cryoloop. Coating the crystal with Parabar can minimize evaporation from the crystal and reduce exposure and slow diffusion of air (oxygen) to the crystal.
HR2-643 Parabar 10312 is no longer available and has been discontinued effective May 11, 2021.
HR2-862 Parabar 10312 is supplied as 5 ml in an amber glass vial with glass applicator rod in screw cap lid.
The viscosity of Parabar can be reduced to improve handling with fragile needle and blade crystals by mixing 50:50 with Paraffin Oil.
Parabar is a blend of polyisobutylenes with a Staudinger molecular weight of about 20,000 and contains about 20% polymer.
Refractive index 1.48487 at 20°C.
Kinematic viscosity 641 cSt at 100°C. Kinematic viscosity ratio 2.05 at 100°C.
Clear to slightly hazy is appearance.

Quartz Capillaries
Applications
- X-ray data collection
- Liquid-liquid diffusion crystallization
- Gel acupuncture crystallization
Features
- Thin walled – 10 micron
- Quartz Glass 0620
Description
Crystal Clear Quartz capillaries that are extremely thin walled (approximately 10 micron wall thickness). The length of the capillary has a well defined diameter, with one end having a funnel shape and the other end closed. Quartz capillaries have a wall thickness of 0.01 mm and an overall length of 80 mm +/-5 mm. Quartz capillaries are available in a wide range of outside diameters from 0.1 mm to 5.0 mm. They are designed to mount, hold, and store small molecule and biological macromolecular crystals for x-ray data collection. Capillaries can also be used for crystal density measurements and crystal growth experiments. The capillaries can be sealed tightly against moisture and gases using wax, epoxy, or other sealing materials.
In determining what glass or quartz capillary is right for you, please refer to the “Linear Absorption Coefficient µ cm-1” table. This table indicates the amount of radiation that is absorbed by the capillary during x-ray data collection.
For 0.1 mm to 2.5 mm capillaries the open end capillary tube base size is 3.0 +/- 0.2 mm OD x 0.2 +/- 0.15 mm Wall thickness. For 3.0 and 3.5 mm capillaries the open end capillary base size is about 4.4 mm OD x 0.25 mm Wall thickness. For 4.0 and 5.0 mm capillaries the open end capillary based size is about 6.0 x 0.25 mm.
The Diameter is measured about 30 to 40 mm from the closed end (measuring instrument: LaserMicrometer LS 7500) The tolerances are as follows.
Diameter Tolerance Minimum Diameter Maximum Diameter
0.1 mm +/-0.05 mm 0.05 mm 0.15 mm

Sodium malonate蛋白结晶试剂盒Hampton Research
Hampton Research蛋白结晶试剂盒
Products > Optimize Reagents > Optimize – Salts > Sodium malonate
Sodium malonate
Applications
- Crystallization grade Sodium malonate for formulating screens or for optimization
Features
- Sterile filtered solution
- Formulated in Type 1+ ultrapure water: 18.2 megaohm-cm resistivity at 25°C, < 5 ppb Total Organic Carbon, bacteria free (<1 Bacteria (CFU/ml)), pyrogen free (<0.03 Endotoxin (EU/ml)), RNase-free (< 0.01 ng/mL) and DNase-free (< 4 pg/µL)
Description
The Sodium malonate offered by Hampton Research is Malonic acid (CAS Number 141-82-2) titrated to pH 4.0-8.0 using Sodium hydroxide as described in the publication “A comparison of salts for the crystallization of macromolecules. Alexander McPherson. Protein Science (2001), 10:418-422.”. In this same publication, Sodium malonate was reported to be more successful than any other salt, resulting in the crystallization of 19 of the 23 macromolecules, almost twice as effective as the next most successful salt, which was a draw between sodium acetate, sodium tartrate, sodium formate, and ammonium sulfate. The high success rate of Sodium malonate in producing crystals was even more impressive when an overall unique success rate with individual macromolecules was considered.
The use of Sodium malonate in place of Ammonium sulfate has been reported in one instance to improve the reproducibility of crystals and improve resistance to physicochemical shocks. Sodium malonate also acted as a good cryoprotectant (Xing and Xu 2003).
One may combine the four different sodium malonate stocks to create a pH versus sodium malonate concentration grid for screening or optimization. Refer to the pH/Dilution Table for Sodium malonate.
Based on the structure of malonic acid titrated with sodium hydroxide, there are no chiral carbons so it is not characterized as having enantiomeric structures, such as D or L.
Synonyms: Propanedioic acid or Malonic acid

1 Doxycycline hyclate is ~87% doxycycline
2 TD.01306 typically ships within 2 days non-irradiated or 2 weeks with irradiation
Considerations when choosing a base diet
- Teklad Global Rodent Diets® like 2018 do not contain alfalfa and are thus ideal if your work requires an alfalfa-free diet for fluorescent imaging, If further imaging clarity is needed, we can make purified diets with doxycycline.
- Teklad global 2018 (base diet in examples above) contains a moderate amount of soybean meal, a source of phytoestrogens. The table below includes several options of minimal phytoestrogen diets with the most common doxycycline concentration of 625 mg/kg diet. For other concentrations contact us. For additional phytoestrogen information, see our list of phytoestrogen references.
Examples of minimal phytoestrogen global rodent diets with doxycycline hyclate1 at 625 mg/kg diet
1 Doxycycline hyclate is ~87% doxycycline
Advantages of diet delivery of doxycycline
- Typically the same doxycycline concentration can be used in diet as in water. Lower concentrations of doxycycline may be adequate with 625 mg/kg diet being the most common concentration.
- Diet offers protection from light. Water may have to be given in dark-colored or foil-wrapped bottles
- Diet is typically changed once per week. Water may need to be changed every few days
- Diet delivery may also reduce risk of dehydration and preclude the need to give with sucrose (Cawthorne et. al. 2007)
Key planning information
- Minimum order quantity is 3 kg, sufficient for feeding ~20 mice for one month
- Store diet refrigerated and plan to use within six months
- Typical lead time is two weeks (four weeks if irradiated)
- TD.01306 typically ships within 2 days non-irradiated or 2 weeks with irradiation
- Irradiation (20 – 50 kGy) is optional, and must be requested at time of order
Safe handling of doxycycline diets
- Doxycycline is a tetracycline class antibiotic.
- Usual dose for therapeutic effects in humans is 100-200 mg/day.
- Doxycycline diets for rodents typically contain ~2 mg/pellet.
- Accidental doxycycline exposure can be minimized by using typical lab precautions of lab coat, gloves, and mask when handling the diet.
- Your chemical safety department should be contacted for additional institution specific guidelines for handling and disposal of doxycycline containing diets.
See our list of doxycycline references for additional information.
Contact us with your specific needs, and we can recommend an existing product code or create a new formulation.

Tacsimate pH 4, 5, 6, 7, 8, & 9
Applications
- Crystallization grade Tacsimate for formulating screens or for optimization
Features
- Sterile filtered solution
- Formulated in Type 1+ ultrapure water: 18.2 megaohm-cm resistivity at 25°C, < 5 ppb Total Organic Carbon, bacteria free (<1 Bacteria (CFU/ml)), pyrogen free (<0.03 Endotoxin (EU/ml)), RNase-free (< 0.01 ng/mL) and DNase-free (< 4 pg/µL)
Description
To screen pH as a crystallization variable using Tacsimate one can mix together different ratios of different pH Tacsimate solutions. Refer to the pdf “Mixing Tacsimate Stocks to Screen pH” on this page. Or, one can add a buffer to the crystallizaiton reagent containing Tacsimate. Recommended final buffer concentration in the reagent well is 0.05 to 0.1 M.
Tacsimate
A pH titrated mixture of organic acids. 1.8305 M Malonic acid, 0.25 M Ammonium citrate tribasic, 0.12 M Succinic acid, 0.3 M DL-Malic acid, 0.4 M Sodium acetate trihydrate, 0.5 M Sodium formate, 0.16 M Ammonium tartrate dibasic. pH adjusted using NaOH

Hampton Research蛋白结晶试剂盒
Products > Crystallization Plates, Hardware & Accessories > Cover Slides & Related Tools > Siliconized Glass Coverslips (Greiner)
Siliconized Glass Coverslips (Greiner)
Applications
- Hanging or sitting drop vapor diffusion crystallization
Features
- High purity of glass
- Siliconized, hydrophobic glass surface
- 0.19-0.22mm glass thickness
- 18 & 22 mm glass diameter
- Circle glass cover slip
- UV imaging compatible (>85% transmission)
Description
Siliconized glass coverslips allow a droplet to be suspended in a position which provides near optimal conditions for vapor diffusion with the surrounding reservoir solution. These siliconized glass cover slides provide a consistent, high quality finish for crystallization experiments. The hydrophobic surface produces a drop which “stands well” and does not flatten on the glass. The siliconized surface prevents the adhesion of crystals and precipitate onto the glass surface. Use vacuum grease or oil to seal cover slide to plate. Available in 18 or 22 mm diameter circles.
HR3-254 is Greiner Bio-One 503870 siliconized glass coverslip, round, 22mm diameter, 0.19-0.22mm thick. Non-sterile. 100 pieces per inner pack. Ten inner packs, totaling 1,000 pieces per packing unit. Fit VDX Plate.

SaltRx 1 • SaltRx 2 • SaltRx HT
Applications
- Primary or secondary, salt and pH matrix crystallization screen for biological macromolecules
Features
- Salt versus pH matrix crystallization screen
- Samples pH 4 to 9
- 22 unique salts versus salt concentration and pH
- Compatible with microbatch, vapor diffusion, liquid & gel diffusion methods
- Tube or Deep Well block format
- Preformulated, ready to screen
- Developed at Hampton Research
- All salts and buffers in screen readily available as Optimize™ reagents for reproducing and optimizing crystals
- Individual reagents available through the Hampton Research Custom Shop
Description
SaltRx was developed by Hampton Research as a primary and secondary, salt and pH based crystallization screen for biological macromolecules.
Salt is the only primary crystallization reagent (precipitant) utilized. Based on a design of 96 conditions, the screen evaluates a broad portfolio of crystallization salts of varying concentration and pH. The selection, concentration, and pH of the salts were determined by data mining the BMCD1 and other crystallization databases, crystallization reports in the literature, and internal crystallization trials performed at Hampton Research. Based on this analysis, up to 35% of protein crystallizations involve salt as the primary crystallization reagent. SaltRx can be used as a primary crystallization screen when salt, ionic strength and pH are desired or suspected as appropriate crystallization variables. It is also useful as a secondary screen when salt only reagents/conditions from screens such as Index™, Crystal Screen™, and Grid Screen™ produce crystals and when further screening for additional salt conditions or optimization is desired. Since this screen does not contain volatile organics, it is compatible with microbatch, vapor diffusion, liquid and gel diffusion crystallization methods. SaltRx may also be used for dialysis crystallization in conjunction with Dialysis Buttons™.
The original SaltRx kit (HR2-108) contained 96 unique reagents, 10 ml each. This kit has been discontinued and converted into two 48 reagent based kits, SaltRx 1 and SaltRx 2, available separately, which when used together are identical to the original SaltRx.
SaltRx 1 contains 48 unique reagents, 10 ml each. SaltRx 1 contains reagents 1-48 of the original SaltRx 96 reagent kit.
Salt Rx 2 contains 48 unique reagents, 10 ml each. SaltRx 2 contains reagent 49-96 of the original SaltRx 96 reagent kit.
SaltRx HT contains the 96 SaltRx 1 and SaltRx 2 reagents in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.
Measured pH range of kit is 4.1 to 9.0 at 25°C
Average measured pH of kit is 6.9 at 25°C
Median measured pH of kit is 7.3 at 25°C
Mode measured pH of kit is 7.4 at 25°C
