青霉素/青霉素钠是一组最初从青霉菌中获得的抗生素,主要是 rysogenum 和 P. rubens。临床使用的大多数青霉素/青霉素钠类药物是由天然生产的青 霉素/青霉素钠类药物化学合成的。一些天然青霉素/青霉素钠已经被发现, 但只有两种纯化的化合物在临床上使用:青霉素/青霉素钠 G(肌肉注射或静 脉注射)和青霉素/青霉素钠 V(口服)。青霉素/青霉素钠类药物是首批对 葡萄球菌和链球菌引起的许多细菌感染有效的药物之一。它们是β-内酰胺类 抗生素的成员。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有青霉素/青霉素钠(Penicillin)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青霉素/青霉素钠(Penicillin)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 Penicillin 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 Penicillin 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.
