干细胞因子又称肥大细胞生长因子(MGF),Kit配体(KL)及Steel因子(SLF),最初是从Buffalo大鼠肝细胞系中cDNA克隆成功,在小鼠MGF基因位于第10号染色体SL基因,是C-kit的配体(C-kit ligand,KL),因此也称之为造血生长因子KL。它是由骨髓微环境中的基质细胞产生的一种酸性糖蛋白。其糖基连在肽键的N和O基团上,相对分子质量31000~36000,由非共价结合的两个相同亚基组成。等电点PI=3.8。SCF共有273个氨基酸。从-25~-1为信号肽,+1~+189为膜外功能区,+190~+216为跨膜区,+217~+248为胞浆功能区。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有小鼠干细胞因子;肥大细胞生长因子(SCF;MGF)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干细胞因子;肥大细胞生长因子(SCF;MGF)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 SCF;MGF. 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 SCF;MGF 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.
