人类白细胞抗原G(HLA-G)为新发现的一类非经典人类白细胞I类抗原,有膜结合型和可溶型两种,主要在母胎界面的绒毛外滋养层细胞上表达,是母体对同种半异体抗原的胎儿免疫应答中的重要耐受分子,其通过与NK细胞以及T细胞的作用而发挥免疫耐受的作用。可溶性白细胞抗原( sHLA)-G在恶性肿瘤患者血浆中的表达水平明显升高,它可能成为一种潜在的肿瘤标记物,在鉴别良恶性肿瘤中发挥重要作用。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人可溶性白细胞抗原G(sHLA-G)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可溶性白细胞抗原G(sHLA-G)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 sHLA-G. 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 sHLA-G 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.
