分泌球蛋白家族3A成员2(SCGB3A2)是一种分泌性肺表面活性蛋白,属于分泌球蛋白家族,主要在呼吸系统的支气管上皮细胞中表达。其基因位于人类染色体5q32,编码的蛋白质是甲状腺转录因子的下游靶标,参与肺表面活性物质的组成与维持,对肺功能具有重要作用。SCGB3A2具有抗炎和抗纤维化活性,能够抑制磷脂酶A2(PLA2G1B)的活性,调节脂质代谢。此外,它还参与胎儿肺的发育和成熟,并在垂体中抑制卵泡刺激素(FSH)和黄体生成素(LH)的产生。该蛋白在哮喘易感性中具有潜在作用,其启动子中的单核苷酸多态性可能与哮喘相关。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人分泌球蛋白家族3A成员2(SCGB3A2)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分泌球蛋白家族3A成员2(SCGB3A2)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 SCGB3A2. 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 SCGB3A2 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.
