CD9是跨膜 4 超家族的成员，也称为跨膜四蛋白家族。它是一种细胞表面糖蛋白，由四个跨膜区域组成，具有两个细胞外环，其中包含在整个跨膜四蛋白家族中保守的二硫键。还包含不同的棕榈酰化位点，允许 CD9 与脂质和其他蛋白质相互作用。跨膜四蛋白参与多种生物过程，例如粘附、运动、膜融合、信号传导和蛋白质运输。CD9 已被证明可以阻止金黄色葡萄球菌粘附到伤口上。 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CD9分子(CD9)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CD9分子(CD9)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 CD9. 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 CD9 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.
