空腹胰岛素(FINS)指在空腹状态下,胰腺所产生胰岛素的量。胰岛素是人体 唯一能够降血糖的物质,在基础状态下无食物、血糖的刺激,也能够以匀定 的速率进行分泌,当进食后变为葡萄糖,吸收入血后刺激胰腺,又能够在短 时间内大量分泌出胰岛素以控制餐后血糖。夜间肝脏会不断输出肝糖原,当 基础胰岛素为对抗肝糖原的输出,才可有正常的空腹血糖。如果没有基础胰 岛素的分泌,空腹血糖会较高,如果没有夜间肝糖原的输出,空腹血糖会较 低。糖尿病患者到晚期后可能会出现基础胰岛素分泌受损,表现为空腹血糖 增高,此时可通过进行胰岛素功能检测,查看胰岛素释放的情况。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有大鼠空腹胰岛素(FINS)抗原的微孔中,依次加入样本、标准品、Biotin标记的抗体,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空腹胰岛素(FINS)呈负相关。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 competitive enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with Rat FINS antigen. The sample, standards, a biotin-labeled antibody, and an HRP enzyme conjugate are then added sequentially to the wells. The procedure includes incubation and wash steps between each addition. TMB substrate is used for color development. In the presence of the peroxidase (HRP) enzyme, TMB is catalyzed to produce a blue color, which is then converted into a final stable yellow color upon the addition of an acid stop solution. The intensity of the resulting yellow color is inversely proportional to the concentration of Rat FINS in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader, and the concentration of the target analyte in the sample is calculated based on the standard curve.
