激肽释放酶原(PK)也被称为弗莱彻因子，是一种丝氨酸蛋白酶，与高分子量的激肽原复合。它是血浆卡利克酶的前体，是一种激活激肽的丝氨酸蛋白酶。它被激活的XII因子（Hageman因子）裂解，产生卡利克雷因。遗传性PK缺陷是非常罕见的。它们可以导致APTT延长，这可以通过培养病人的血浆而得到纠正。PK缺陷也可因某些疾病状态而获得，如血管性水肿、感染、DIC和镰状细胞病。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人激肽释放酶原(PK)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激肽释放酶原(PK)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 PK. 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 PK 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.
