Runt相关转录因子2（RUNX2）也被称为核心结合因子亚单位α-1（CBF-α-1），是一种在由RUNX2基因编码的蛋白质。RUNX2是一个与成骨细胞分化有关的关键转录因子。该蛋白是RUNX转录因子家族的成员，有一个Runt DNA结合域。它对成骨细胞的分化和骨骼形态的形成至关重要。它作为核酸和参与骨骼基因表达的调节因子的支架。该蛋白既可以作为单体与DNA结合，也可以作为异源二聚体复合物的亚单位，具有更强的亲和力。编码不同蛋白异构体的基因的转录变体是由使用交替的启动子和交替的剪接造成的。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有小鼠Runt相关转录因子2(RUNX2)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小鼠Runt相关转录因子2(RUNX2)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 Mouse RUNX2. 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 Mouse RUNX2 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.
