骨成型蛋白4(BMP4)是一种蛋白质,它是一种属于TGF-β超家族蛋白的多肽。它和其他骨成型蛋白一样,参与骨和软骨的发育,特别是牙齿和肢体的发育以及骨折修复。BMP4在进化上是高度保守的,它是一种旁分泌生长因子,已在大鼠卵巢中发现。BMP4与BMP7共同调节早期卵巢卵泡的发育和原始卵泡向初级卵泡的转化。此外,用抗体抑制BMP4已被证明能减少整个卵巢的大小。这些结果表明,BMP4可能有助于卵母细胞的存活和防止细胞凋亡。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有大鼠骨成型蛋白4(BMP4)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骨成型蛋白4(BMP4)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 BMP4. 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 BMP4 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.
