白细胞介素 1α(IL-1α)也被称为造血素 1,是白细胞介素 1 家族的一种细胞因子,在人类中由 IL1A 基因编码。一般来说,白细胞介素 1 负责产生炎症,以及促进发烧和败血症。目前正在开发 IL-1α抑制剂以中断这些过程和治疗疾病。IL-1α主要由活化的巨噬细胞,以及中性粒细胞、上皮细胞和内皮 细胞产生。它具有代谢、生理和造血活性,并在免疫反应的调节中发挥核心作用。它与白细胞介素-1 受体结合。它是激活肿瘤坏死因子-α的途径。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人白细胞介素1α(IL-1α)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白细胞介素1α(IL-1α)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 IL-1α. 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 IL-1α 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.
