Gremlin-1蛋白(GREM1)是一种高度保守的20.7kDa,184个氨基酸的糖蛋白,属于DAN家族,是一种半胱氨酸结分泌的蛋白。它因其在TGF beta信号传导途径中与骨形态发生蛋白(BMPs)的拮抗作用而闻名。它主要抑制肢体芽中的BMP2和BMP4,并作为自我调节反馈信号系统的一部分发挥作用,这对正常的肢体芽发育和指头形成至关重要。它在肢体芽中对BMPs的抑制使成纤维细胞生长因子(FGFs)4和8以及声猬(SHH)配体的转录上调,这是控制肢体芽发育进展的信号系统的一部分。 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Gremlin-1蛋白(GREM1)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Gremlin-1蛋白(GREM1)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 GREM1. 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 GREM1 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.
