表皮生长因子(EGF)是一种由53个氨基酸残基组成的耐热单链低分子多肽。EGF与靶细胞上的EGF受体特异性识别结合后,发生一系列生化反应,最终可促进靶细胞的DNA合成及有丝分裂。EGF通过与其同源受体结合,导致细胞增殖、分化和存活。唾液中的EGF似乎受到饮食中无机碘的调节,在维持口食道和胃组织的完整性方面也发挥着重要的生理作用。唾液中的EGF的生物学作用包括:治愈口腔和胃食道溃疡,抑制胃酸分泌,刺激DNA合成,以及保护粘膜免受胃酸、胆汁酸、胃蛋白酶和胰蛋白酶等腔内损伤性因素的影响,以及保护粘膜免受物理、化学和细菌制剂的影响。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有大鼠表皮生长因子(EGF)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表皮生长因子(EGF)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 EGF. 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 EGF 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.
