干扰素刺激基因15(ISG15)是一种17kDA的分泌蛋白,由ISG15基因编码。它由I型干扰素(IFN)诱导,具有许多功能,既是细胞外细胞因子,又是细胞内蛋白修饰剂。确切的功能是多种多样的,在不同的物种中有所不同,但包括增强淋巴细胞中干扰素γ(IFN-II)的产生,对新合成的蛋白质进行类似泛素的结合,以及对IFN-I反应进行负向调节。未成熟的多肽在其羧基末端被裂解,产生一个15 kDa的成熟产物,其末端有一个LRLRGG图案,就像在泛素中发现的那样。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人类泛素蛋白(ISG15)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类泛素蛋白(ISG15)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 ISG15. 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 ISG15 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.
