Application | BrdU Cell Proliferation Assay |
BrdU Proliferation Assay involves incorporation of BrdU into cells cultured in microtiter plates using the cell layer as the solid phase. During the final 2 to 24 hours of culture BrdU is added to wells of the microtiter plate. BrdU will be incorporated into the DNA of dividing cells. To enable antibody binding to the incorporated BrdU cells must be fixed, permeabilized and the DNA denatured. This is all done in one step by treatment with Fixing Solution. Detector anti-BrdU monoclonal antibody is pipetted into the wells and allowed to incubate for one hour, during which time it binds to any incorporated BrdU. Unbound antibody is washed away and horseradish peroxidase-conjugated goat anti-mouse antibody is added, which binds to the Detector Antibody.
The horseradish peroxidase catalyzes the conversion of the chromogenic substrate tetra-methylbenzidine (TMB) from a colorless solution to a blue solution (or yellow after the addition of stopping reagent), the intensity of which is proportional to the amount of incorporated BrdU in the cells. The colored reaction product is quantified using a spectrophotometer.

第二步、明确编码该蛋白的基因与其它哪些物种同源性最好
第三步、寻找检测这些物种蛋白的试剂盒
第四步、咨询商家ELISA是试剂盒使用的抗体类型:多抗还是单抗? 单抗是针对什么抗原决定簇的?
第五步、 做出自己的判断该买哪个试剂盒,或者实在没有可以找公司进行订制实验
的试剂:免疫吸附剂、结合物和酶的底物。
完整的ELISA试剂盒包含以下各组分:
(1)已包被抗原或抗体的固相载体(免疫吸附剂);
(2)酶标记的抗原或抗体(结合物);
(3)酶的底物;
(4)阴性对照品和阳性对照品(定性测定中),参考标准品和控制血清(定量测定
中);
(5)结合物及标本的稀释液;
(6)洗涤液;
(7)酶反应终止液。
1、是不是获得SCI文献引用;
2、试剂盒是不是具备高灵敏,质量好的;
3、售后服务完全,提供代测服务;
4、后期实验提供全程技术支持!
