二、保存及运输条件:

1. 保持容器密闭

2. 储存温度2 °C - 8 °C,避光

3. 只保留/储存在原始容器中

4. 切勿将溢出的液体放入原容器中重复使用

5. 应远离食品和饲料

6. 在环境温度不超过 30 °C,运输时间应少于一周。

7. 从损坏的瓶子中污染或泄漏的基质溶液不可再使用,须销毁。

8.过期后,溶液仍可使用,但是产品活性可能会降低;

 

三、有效成分及生化机理

本产品以柠檬酸为缓冲体系(pH 5.0),含有以下有效成分

过氧化氢(<3.0 mM)

3,3 ',5,5 ' -四甲基联苯胺(TMB, 1.2 mM)

沉淀剂(5 g/l)

过氧化物酶催化过氧化氢的分解,从TMB获得电子(通过氧化)。TMB的氧化形成一个自由基阳离子,通过二聚化而稳定,并显示出典型的蓝色。这些蓝色阳离子通过与沉淀试剂形成不可溶的络合物而稳定下来。所以在具有辣根过氧化物酶活性的位置会出现蓝色到紫色的沉淀。


四、生物安全信息

根据法规(EC) No 1272/2008,本产品不属于危险类别;

混合物中的物质不符合REACH附件XIII规定的PBT/vPvB标准。

 

五、主要优点

1. 由于高活性而快速形成沉淀

2. 非常低的背景有助于形成高度的对比

3. 深蓝色沉淀

4. 反应停止后无明显褪色

5. 膜剥离后的膜用于进一步的免疫反应

 

六、使用说明

关于分装的建议

•在没有灰尘和黑暗的房间工作。

•注意溶液不要接触到仪器金属部件(导致催化) ,硅管的封闭系统是有利的。

•仔细清洁所有的仪器和容器。

•不要用裸露的手触摸与溶液接触的仪器部分。戴无粉手套。

•立即关闭瓶子,尽量减少光线和灰尘的影响。

•使用由高密度聚乙烯或聚丙烯制成的不透光的瓶子。

 

七、使用的一般说明

只有熟悉免疫学方法基础的合格实验室工作人员才能使用该产品。

本产品适用于具有视觉解释的印迹反应体系。在规定的条件下,可进行密度测量。

根据反应体系的不同,在将测试条转移到底物溶液之前,用共轭物孵育后洗涤液充分洗涤测试条,测试带通过在轨道振荡器上移动而显影,出现明显的颜色。

大多数商业膜都可以清洗和干燥。在干燥的条带上可以看到最佳的颜色对比。干燥的条状可用于记录。 (注意:某些胶体会破坏有色沉淀物。

2、Requirements for storage rooms and vessels

1.Keep container tightly closed.

2.Keep cool. protected from light

3.Keep/Store only in original container.

4.Never return spills in original containers for reuse.

5. Keep away from: Food and feeding stuffs

6. It is possible to transport the solution at ambient temperature, unless it does not exceed 30 °C. The transport should take less than one week.

7. Contaminated or leaked out substrate solution from damaged bottles should not be used anymore and has to be destroyed.

8.The solution still works even beyond the expiry date, but a lower activity has to be taken in account.

 

3、Effective Components and Principle of Function

A citrate buffer system (pH 5.0) contains the following effective components

· Hydrogen peroxide (<3.0 mM)

· 3,3`,5,5`-Tetramethylbenzidine (TMB, 1.2 mM)

· precipitating reagent ( 5 g/l)

 

Peroxidase catalyses the decomposition of hydrogen peroxide, taking electrons from TMB (oxidation). By oxidation TMB forms a radical cation that stabilizes by dimerisation and shows the typical blue colour.

These blue cation is stabilized by forming a insoluble complex with the precipitating reagent. So at positions with activity of horseradish peroxidase a blue to violet precipitate will appear.

 

4、Biosafety information

This mixture is not classified as hazardous in accordance with Regulation (EC) No 1272/2008;

The substances in the mixture do not meet the PBT/vPvB criteria according to REACH, annex XIII.

 

5、Advantage

1. Rapid precipitate formation due to high activity

2. Very low background contributes to a high contrast

3. Dark blue precipitates

4. No significant fading after reaction stop

5. MembraneReuse of membranes after stripping for further immune

 

6、Instruction for usage

For bottling consider the following instructions:

• Work in a dust free and darkened room.

• Pay attention that the solution has no contact with metal parts (leading to catalysis) of your instruments. Closed systems of silicon tubes are favoured.

• Clean all instruments and vessels very carefully.

• Never touch parts of the instruments that are in contact with the solution with the naked hand. Wear powder free gloves.

• Close the bottles immediately to minimize the influence of light and dust.

• Use bottles that are not permeable to light, made from HDPE or PP.

 

7、 General Instructions for the Use in Blotting Systems 

Only qualified laboratory staff, who are familiar with the basics of immunological methods, are allowed to use this solution.

The substrate solution is intended for the use in blotting systems with visual interpretation. Under defined conditions a densitometric measurement is possible.

Depending from the system it is sufficient to wash the test strips after incubation with conjugate prior to transfer into the substrate solution. The strips are developed by movement on an orbital shaker until a distinct colour appears.

The most commercial membranes allow to be washed and dried and the dried strips may be stored for documentary purposes. (Pay attention: some glues destroy the coloured precipitate)
