解整合素金属蛋白酶17(ADAM17)也叫TACE(肿瘤坏死因子-α转化酶),是一种70kDa的酶,属于崩解素和金属蛋白酶的ADAM蛋白家族。它参与处理细胞表面的肿瘤坏死因子α(TNF-α),并从跨高尔基体网络的细胞内膜中取出。这个过程也被称为 "脱落",涉及到从膜结合的原蛋白(如原TNF-α)中裂解和释放一个可溶性的外域,并且具有已知的生理重要性。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人解整合素金属蛋白酶17(ADAM17)捕获抗体的微孔中,依次加入样本、标准品、生物素标记的检测抗体,HRP酶结合物,中间经过温育和洗涤,用底物TMB显色,TMB在过氧化物酶(HRP)的催化下转化成蓝色,并在酸的作用下转化成最终的黄色。颜色的深浅和样本中的人解整合素金属蛋白酶17(ADAM17)呈正相关。用酶标仪在450nm 波长下测定吸光度(OD值),计算样本浓度。
This kit employs the sandwich enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with a capture antibody specific to Human ADAM17. Following this, the sample, standards, a biotin-conjugated detection antibody, and an HRP (horseradish peroxidase)-labeled conjugate are added sequentially to the wells. The procedure involves incubation and wash steps between each addition. For detection, TMB substrate is used. TMB yields a blue color in the presence of the peroxidase activity of HRP. The reaction is then stopped with an acid solution, which converts the blue color to a final yellow color. The intensity of the yellow color is directly proportional to the concentration of Human ADAM17 present in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader. Finally, the concentration of the target analyte in the sample is calculated based on the standard curve generated from the standards.
