中性粒细胞明胶酶相关脂质运载蛋白(NGAL)是一种由LCN2基因编码的蛋白质。NGAL通过封存铁并阻止细菌使用，从而限制其生长，参与先天免疫。 它在中性粒细胞中表达，在肾脏、前列腺、呼吸道和消化道的上皮细胞中也有低水平表达。在急性肾损伤（AKI）的情况下，NGAL会在损伤后2小时内高水平地分泌到血液和尿液中。AKI患者的NGAL水平与他们的预后严重程度有关，可作为AKI的生物标志物，NGAL也可作为慢性肾脏病、造影剂诱导的肾病和肾移植等手术的早期诊断。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人中性粒细胞明胶酶相关脂质运载蛋白(NGAL)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中性粒细胞明胶酶相关脂质运载蛋白(NGAL)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 NGAL. 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 NGAL 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.
