血小板衍化生长因子BB(PDGF-BB)是在骨骼细胞中研究得比较广泛的异构体。由活化的血小板和巨噬细胞产生的PDGF-BB是迄今为止唯一被证明可以选择性地直接促进音型转换的因素。30年前,Blank和Owens以及其他人(Li等,1997年)相继证明,用PDGF-BB处理VSMCs与多种分化标记基因的快速下调有关。总之,PDGF刺激VSMC增殖和迁移。PDGF受体的作用已在损伤后的模型中得到描述。PDGF还间接地诱导其他生长因子的合成,如EGF和FGF-2,从而引起更长期的激活。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人血小板衍化生长因子BB(PDGF-BB)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小板衍化生长因子BB(PDGF-BB)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 PDGF-BB. 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 PDGF-BB 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.
