高密度脂蛋白( high-density lipoprotein，HDL) 为血清蛋白之一，是由脂质和蛋白质及其所携带的调节因子组成的复杂脂蛋白，亦称为a1脂蛋白。高密度脂蛋白HDL主要由肝和小肠合成。肝合成的新生HDL以磷脂和ApoAⅠ为主。在LCAT作用下，游离胆固醇变成胆固醇酯，脂蛋白则变成成熟球形HDL3，再经LPL作用转变成HDL2。LCAT通过转酯化反应完成新生盘状HDL向HDL3、HDL2的转化，减少血浆HDL中游离胆固醇的浓度，构成胆固醇从细胞膜流向血浆脂蛋白的浓度梯度，降低组织胆固醇的沉积。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有大鼠高密度脂蛋白3(HDL3)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高密度脂蛋白3(HDL3)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 HDL3. 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 HDL3 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.
