血管性血友病因子（vWF）是一种参与止血的血液糖蛋白，特别是血小板粘附。它在Von Willebrand病中缺乏和/或有缺陷，并参与许多其他疾病，包括血栓性血小板减少性紫癜、海德氏综合征，以及可能的溶血性尿毒症。vWF也是一种存在于血浆中的大型多聚体糖蛋白，在内皮细胞（在Weibel-Palade体内）、巨核细胞（血小板的α颗粒）和内皮下结缔组织中组成性地产生超大型vWF。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人血管性血友病因子(vWF)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血管性血友病因子(vWF)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 vWF. 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 vWF 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.
