  OCT冰冻切片包埋剂（O.C.T. Compound）
  OCT冰冻切片包埋剂是一种聚乙二醇和聚乙烯醇的水溶性混合物，目前已广泛用于免疫组化实验室中，其用途是在冰冻切片时支撑组织，以增加组织的连续性，减少皱折及碎裂。又因OCT混合物为水溶性，故在漂片时可溶于水，所以在以后的染色中不会增加背景染色。
  规格：100ml

Sakura樱花OCT包埋剂Compound Tissue-Tek

OCT冰冻切片包埋剂（O.C.T. Compound）

利用OCT混合物（opti-mum cutting temperature compound）预先浸润组织，然后再进行恒冷箱切片，使切片质量得到改善。

OCT包埋剂（SAKURA产品，MADE IN USA）包埋流程:

1. 将放在蔗糖溶液中的组织块取出，放入20g L-1 蔗糖与OCT包埋剂1：1体积比例混合液中，室温浸泡2h

2. 移入OCT包埋剂中室温浸泡4h，更换新的OCT包埋剂，室温浸泡6h.

3. 将标本置于托物台，用恒冷箱切片机切片（一般-22℃），片厚10μm，贴于预处理的载玻片上，-20℃冰箱保存。

DAKO一抗稀释液Antibody Diluent, Background Reducing

• 产品型号：  Dako s3022 Dako代理
• 简单描述
• for dilution of antibodies which tend to give high, non-specific background staining in immunohistochemical procedures.Diminishes background staining while maintaining adequate,specific staining

DAKO一抗稀释液Antibody Diluent, Background Reducing

*的一抗稀释液

DAKO一抗稀释液Antibody Diluent, Background Reducing说明：

Intended use For In Vitro diagnostic use.
This product is intended for use as a diluent in the preparation of primary antibodies and negative control
reagents. It is to be used with antibodies and/or antigens that yield high background in immunohistochemical
（IHC） staining procedures.
Refer to the “General Instructions for Immunohistochemical Staining” or the Detection System “Instructions” of
IHC procedures for: （1） Principle of Procedure, （2） Materials Required, Not Supplied, （3） Storage, （4） Specimen
Preparation, （5） Staining Procedure, （6） Quality Control, （7） Troubleshooting, （8） Interpretation of Staining,
（9） General Limitations.
Reagent provided 0.05 mol/L Tris-HCl buffer containing 0.1% Tween, stabilizing proteins to reduce background, and 0.015 mol/L
sodium azide.
Precautions 1. For professional users.
2. This product contains sodium azide （NaN3）, a chemical highly toxic in pure form. At product concentrations,
though not classified as hazardous, build-ups of NaN3 may react with lead and copper plumbing to form
highly explosive metal azides. Upon disposal, flush with large volumes of water to prevent azide build-up in
plumbing.1,2
3. Wear appropriate Personal Protective Equipment to avoid contact with eyes and skin.
4. Unused solution should be disposed of according to local, State and Federal regulations.
Reactivity For demonstration of tissue antigens by IHC, optimal staining performance is dependent on the correct dilution
of the primary antibody. The interaction between antibodies and epitopes consists mainly of relatively weak
forces such as van der Waals forces, electrostatic forces and hydrophobic forces, which are influenced by pH
and ionic strength. Consequently, to assure optimal performance of the antibody with the least amount of
background, the choice of diluent is important.
Applications This product provides an appropriay buffered solution for the dilution of both polyclonal and monoclonal
antibodies and for the preparation of negative control reagents in IHC. This product is particularly useful for
reducing background staining while maintaining specific reactivity. Antibody Diluent with Background Reducing
Components can also be used to stabilize diluted antibodies when stored at 2–8°C. This diluent should be
brought to room temperature and mixed thoroughly prior to use.
Limitations Tissue staining results are dependent upon the handling and processing of the tissue prior to staining.
Aldehyde-containing fixatives, such as formalin and glutaraldehyde frequently contribute to increased
background staining. Improper fixation, freezing, thawing, washing, drying, heating or sectioning may produce
artifacts, antibody trapping or false-negative results. Also, false-positive staining may be caused by crossreactivity
of other IHC staining reagents to e.g. endogenous alkaline phosphatase, endogenous peroxidase,
pseudoperoxidase, endogenous avidin-binding activity and/or by nonspecific reaction with necrotic or
degenerated cells.
Storage Store at 2–8°C. Do not freeze.
