APO-A（载脂蛋白A）是高密度脂蛋白（HDL）的主要结构蛋白，在脂质代谢和心血管健康中发挥重要作用。载脂蛋白A通过结合胆固醇并促进其逆向转运至肝脏代谢，帮助清除血管壁中的胆固醇沉积。APO-A家族包括A1、A2、A4和A5等亚型，其中Apo A1最重要，占HDL蛋白总量的70%以上。它通过激活LCAT酶促进胆固醇逆向转运，将外周组织胆固醇运至肝脏代谢，从而抗动脉粥样硬化。Apo A1还具有抗炎、抗氧化功能，其水平降低与冠心病、糖尿病风险相关，升高则可能提示心血管保护作用。临床主要检测Apo A1与Apo B的比值是评估心血管风险的重要指标。其他亚型如Apo A2、A5分别与胰岛素抵抗和甘油三酯代谢相关。APO-A检测对血脂异常和动脉粥样硬化疾病的诊疗具有重要价值。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有大鼠糖化载脂蛋白A(GApo-A)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大鼠糖化载脂蛋白A(GApo-A)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 Rat GApo-A. 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 Rat GApo-A 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.
