西罗莫司(Estradiol,Sirolimus),也称为雷帕霉素(Rapamycin)、是一种大环内酯类化合物,用于涂覆冠状动脉支架、防止器官移植排斥反应、治疗一种称为淋巴管平滑肌瘤病的罕见肺部疾病,以及治疗血管周围上皮样细胞瘤 (PEComa)。它在人类中具有免疫抑制功能,在防止肾移植排斥反应方面特别有用。它是雷帕霉素 (mTOR) 激酶抑制剂的哺乳动物靶标,可降低 T 细胞和 B 细胞对白细胞介素-2 (IL-2) 的敏感性,从而抑制其活性。作为蛋白质结合颗粒,适用于治疗患有局部晚期不可切除或转移性恶性血管周围上皮样细胞瘤 (PEComa) 的成人患者。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有西罗莫司(Sirolimus)抗原的微孔中,依次加入样本、标准品、Biotin标记的抗体,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西罗莫司(Sirolimus)呈负相关。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 competitive enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with Sirolimus antigen. The sample, standards, a biotin-labeled antibody, and an HRP enzyme conjugate are then added sequentially to the wells. The procedure includes incubation and wash steps between each addition. TMB substrate is used for color development. In the presence of the peroxidase (HRP) enzyme, TMB is catalyzed to produce a blue color, which is then converted into a final stable yellow color upon the addition of an acid stop solution. The intensity of the resulting yellow color is inversely proportional to the concentration of Sirolimus in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader, and the concentration of the target analyte in the sample is calculated based on the standard curve.
