用于抗原、抗体与辣根过氧化物酶的偶联,具有简便、快速的特点。
反应原理
试剂盒中冻干的辣根过氧化物酶经过过碘酸钠活化后,含有大量游离醛基,可以直接与抗原、抗体上的氨基在弱碱性条件(启动剂调节)下反应生成 Schiff 碱,其经过还原剂还原可以形成稳定的化学键。

3. 试剂盒其他组分使用后要及时放回到 2~8℃条件,在试剂盒有效期内使用。
待标记物要求
1. 如果使用叠氮钠为防腐剂,则材料必须使用 0.01M PBS(pH7.4)透析。
2. 溶剂中含有尿素、甘氨酸、Tris、硫酸铵等含氨基的蛋白材料在标记前必须使用 0.01M PBS(pH7.4)透析。
3. 待标记物的纯度过低影响标记效率,建议对待标记物做进一步纯化。
4. 待标记物中如有沉淀物,可能会影响标记效率,建议高速离心或过滤去除,并确定未变质后方可使用。

Intended Use
For the conjugation of antigens and antibodies with horseradish peroxidase (HRP), featuring simplicity and rapidity.
Reaction Principle
The lyophilized horseradish peroxidase in the kit is activated by sodium periodate, resulting in a large number of free aldehyde groups. These aldehyde groups can directly react with amino groups on antigens and antibodies under weakly alkaline conditions (adjusted by the initiator) to form Schiff bases, which can be reduced by a reducing agent to form stable chemical bonds.
Storage Conditions and Shelf Life
1、The kit shall be protected from strong light. It is valid for 6 months when stored at 2–8℃, and 18 months when stored at -20℃.
2、Once opened, the lyophilized HRP vial can be used for 2 days if stored at 2–8℃.
3、Other components of the kit shall be promptly returned to 2–8℃ after use, and must be used within the kit’s shelf life.
Requirements for Analytes to Be Labeled
1、If sodium azide is used as a preservative, the material must be dialyzed against 0.01 M PBS (pH 7.4).
2、Protein materials containing amino groups such as urea, glycine, Tris, and ammonium sulfate in the solvent must be dialyzed against 0.01 M PBS (pH 7.4) prior to labeling.
3、Low purity of the analyte will compromise labeling efficiency; further purification of the analyte is recommended.
4、Precipitates in the analyte may affect labeling efficiency. It is recommended to remove them by high-speed centrifugation or filtration, and use only after confirming no deterioration.
Labeling Protocol
A. Experimental Preparation
a) Remove the kit from refrigerated or frozen storage, equilibrate at room temperature (18–25℃) for 20–30 minutes. Allow liquid components to fully thaw and reach room temperature, then vortex to mix before use.b) The recommended antibody concentration is 0.5 mg/mL–5.0 mg/mL.c) For antigen labeling, optimization of the optimal labeling ratio is required.
B. Experimental Procedure
a) Antibody Preparation: Before use, dilute (or concentrate) the antibody with 0.01 M PBS (pH 7.4) to the specified concentration listed in the appendix.
b) Conjugation: Add the antibody to the lyophilized enzyme, followed by the corresponding volume of initiator. Vortex thoroughly until the lyophilized enzyme is completely dissolved, then incubate at room temperature in the dark for 2 hours.
c) Reductant Preparation: Add 60 μL of initiator to 1400 μL of purified water and vortex to mix. Pipette 1 mL of this diluted solution into the reductant to obtain a 10 mg/mL reductant solution.
d) Reduction: Immediately add the corresponding volume of reductant solution to the reacted enzyme-labeled conjugate, and incubate at room temperature in the dark for 2 hours.
e) Termination: Add the corresponding volume of stop solution, mix well, and incubate at room temperature in the dark for 10 minutes.f) Storage: Add an equal volume of glycerol, mix thoroughly, and store at -20℃.
Operating Procedure (Example: Labeling 0.2 mg of antibody at a concentration of 5 mg/mL)

Precautions
1、Carefully read the instruction manual before operation, and perform the test strictly in accordance with the kit instructions.
2、Avoid conducting tests in harsh environments (such as environments containing corrosive gases and dust like 84 disinfectant, sodium hypochlorite, acid-base, or acetaldehyde).
3、The reducing agent must be prepared freshly for immediate use; dissolve it with the initiator dilution and use promptly. Discard the reducing agent immediately with the cap open after use.
4、Wear disposable gloves when handling reagents, and wash hands thoroughly after operation.
5、Please use the reagents within their validity period.
