Sacituzumab govitecan 是一种 Trop-2 定向抗体和拓扑异构酶抑制剂药物偶联物,这意味着该药物靶向帮助癌症生长、分裂和扩散的 Trop-2 受体,并与拓扑异构酶抑制剂有关,拓扑异构酶抑制剂是一种对癌细胞有毒的化合物。全球大约每 10 例乳腺癌诊断中就有 2 例是三阴性。三阴性乳腺癌是一种雌激素受体、孕激素受体和人表皮生长因子受体 2 (HER2) 蛋白检测呈阴性的乳腺癌。因此,三阴性乳腺癌对激素治疗药物或靶向 HER2 的药物没有反应。 本试剂盒采用间接法酶联免疫吸附试验(ELISA)。往预先包被有人TROP-2抗原的微孔中,依次加入样本、标准品、HRP标记的二抗,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戈沙妥珠单抗(Sacituzumab Govitecan)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 indirect enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with Human TROP-2 antigen. The sample or standard is first added to the wells, followed by an HRP (horseradish peroxidase)-labeled secondary antibody. The procedure involves incubation and wash steps between each addition. TMB substrate is then added for color development. Under the catalysis of the peroxidase (HRP), TMB is converted into a blue product, which subsequently turns into a final stable yellow color upon the addition of an acid stop solution. The intensity of the yellow color is directly proportional to the concentration of Sacituzumab Govitecan 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.
