碱性磷酸酶(ALP, ALKP, ALPase, Alk Phos)是一种 86 千道尔顿的同源蛋白酶。每个单体含有五个半胱氨酸残基、两个锌原子和一个镁原子,对其催化功能至关重要,它在碱性 pH 环境下具有最佳的活性。它具有去磷酸化化合物的生理作用。这种酶在众多的生物体中被发现,包括原核生物和真核生物,具有相同的一般功能,但有不同的结构形式,适合它们的功能环境。它存在于大肠杆菌的周质空间。这种酶具有热稳定性,在高 pH 值下具有最大的活性。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有牛碱性磷酸酶(ALP)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牛碱性磷酸酶(ALP)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 Bovine ALP 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 Bovine ALP 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.
