瘦素是一种主要由脂肪细胞和小肠的肠细胞制造的激素,通过抑制饥饿感来帮助调节能量平衡,这反过来又减少了脂肪细胞的脂肪储存。脂肪细胞特异性激素瘦素的中心作用(效果)位置是下丘脑,它是大脑的一部分,属于中枢神经系统。瘦素的非下丘脑目标被称为外周目标。在不同的生理状态下,中枢和外周瘦素的相互作用有不同的相对重要性,在不同的物种之间也有差异。瘦素的主要功能是通过下丘脑中枢对饥饿感、食物能量利用、体育锻炼和能量平衡的影响来调节脂肪组织的质量。在大脑之外,在身体的外围,瘦素的次要功能是:调节能量消耗,调节胎儿和母亲的代谢,以及青春期的容许因子,免疫细胞的激活剂,β胰岛细胞的激活剂,以及生长因子。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人瘦素(LEP)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瘦素(LEP)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 LEP. 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 LEP 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.
