肿瘤坏死因子β(TNF-β),又叫淋巴毒素-α(LT-α),是一种类细胞因子,是由LTA基因编码的蛋白质。它属于造血细胞系,它表现出抗增殖活性并导致肿瘤细胞系的细胞破坏。作为一种细胞毒性蛋白,它在免疫调节中具有多种重要作用,这取决于其分泌的形式。与TNF超家族的其他成员不同,它仅被发现为可溶性同种三聚体,当在细胞表面发现时,它仅被发现为与LTβ的异质三聚体。它免疫系统的维持有重大影响,包括继发性淋巴器官的发育。缺乏LT-α会导致胃肠道发育中断,阻止Peyer的贴片发育,并导致脾脏紊乱。它参与细胞存活、增殖、分化和凋亡的调节。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有小鼠肿瘤坏死因子β(TNF-β)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肿瘤坏死因子β(TNF-β)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 TNF-β. 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 TNF-β 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.
