白细胞介素-18(IL18,又称干扰素-γ诱导因子)是一种蛋白质,由IL18基因编码。 该基因编码的蛋白质是一种促炎症细胞因子。许多细胞类型,包括造血细胞和非造血细胞,都有可能产生IL-18。最初,IL-18的产生是在Kupffer细胞、肝脏驻留的巨噬细胞中被认可。然而,IL-18在非造血细胞,如肠道上皮细胞、角质细胞和内皮细胞中也有构成性表达。 IL-18可调节先天性和适应性免疫,其失调可引起自身免疫性或炎症性疾病。IL-18属于IL-1超家族,主要由巨噬细胞产生,但也有其他类型的细胞,刺激各种类型的细胞,具有多种功能。IL-18是一种促炎症细胞因子,有利于1型反应。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有小鼠白细胞介素18(IL-18)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小鼠白细胞介素18(IL-18)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 Mouse IL-18. 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 Mouse IL-18 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.
