前蛋白转化酶枯草溶菌素4,也被称为PCSK4,是由PCSK4基因编码的酶。该基因编码枯草杆菌样前蛋白转换酶家族的成员,该家族包括蛋白酶,其通过分泌途径的调节或构成分支处理蛋白质和肽前体的运输。编码的蛋白质在ER中经历初始的自催化处理事件,以产生一种异源二聚体,该异源二聚体离开ER并分类到亚细胞区室,在那里甚至发生第二次自催化并获得催化活性。该基因编码七种碱性氨基酸特异性成员之一,这些成员在单个或成对的碱性残基上切割其底物。蛋白酶仅在睾丸、胎盘和卵巢中表达。它在受精、胎质生长和胚胎发育中起着关键作用,并处理多种激素原,包括垂体腺苷酸原环化酶激活蛋白和胰岛素样生长因子II。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人前蛋白转化酶枯草溶菌素4(PCSK4)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前蛋白转化酶枯草溶菌素4(PCSK4)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 PCSK4. 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 PCSK4 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.
