VEGF121是VEGF-A的第二个最丰富的剪接变体。它由内皮细胞、巨噬细胞、T细胞和其他细胞类型产生，并且参与血管生成、血管内皮细胞的生存、生长、迁移和血管通透性。它的表达是由缺氧、炎症细胞因子和通过肿瘤中的癌基因产物诱导的。VEGF121与VEGFR1和VEGFR2受体酪氨酸激酶结合，它与VEGFR1和VEGFR2的结合导致涉及PI3K/AKT、P38 MAPK和FAK的途径的激活。 本试剂盒采用双抗体夹心法酶联免疫吸附试验（ELISA）。往预先包被有大鼠血管内皮生长因子121(VEGF121)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大鼠血管内皮生长因子121(VEGF121)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 Rat VEGF121. 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 Rat VEGF121 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.
