脂肪酸结合蛋白4（FABP4），也被称为脂肪细胞FABP（A-FABP）或aP2，主要在脂肪细胞和巨噬细胞中表达，在与元炎有关的胰岛素抵抗和动脉粥样硬化的发展中起着重要作用。FABP4缺乏典型的分泌信号肽，但在与脂肪分解相关的非经典途径中从脂肪细胞中释放，可能作为一种脂肪因子。脂肪酸结合蛋白是一类高度保守的小细胞质蛋白，可结合长链脂肪酸和其他疏水配体。人们认为 FABP 的作用包括脂肪酸摄取、转运和代谢。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人脂肪细胞型脂肪酸结合蛋白(FABP4)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脂肪细胞型脂肪酸结合蛋白(FABP4)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 FABP4. 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 FABP4 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.
