凝血酶原片段1+2（F 1+2）是凝血酶原分子的氨基末端片段。当凝血酶被凝血酶复合物转化为凝血酶时，F 1+2会从凝血酶中释放出来，它是一种多肽，半衰期约为90分钟。凝血酶的激活是在Xa因子、Va因子、钙离子和磷脂表面（血小板）的存在下进行的。在凝血酶形成过程中，凝血酶原片段F1+2可以通过两种方式产生。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有人凝血酶原片段F1+2(F1+2)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凝血酶原片段F1+2(F1+2)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 F1+2. 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 F1+2 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.
