Ⅲ型胶原(ColⅢ)是一个同源三聚体,或由三个相同的肽链(单体)组成的蛋白质,每个都称为III型胶原蛋白的α1链。从形式上看,这些单体被称为III型胶原蛋白,α-1链,由COL3A1基因编码。III型胶原蛋白是纤维状胶原蛋白之一,其蛋白质有一个长的、不灵活的、三螺旋结构域。三螺旋构象是所有纤维状胶原蛋白的一个特征,它之所以可能是因为在大约1000个氨基酸的序列中,每三个氨基酸就有一个甘氨酸。它除了是许多器官不可或缺的结构成分外,它也是I型和II型胶原蛋白纤维直径的重要调节剂。而且,它还通过与血小板结合促进血小板聚集,因此在血液凝固中发挥重要作用。 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Ⅲ型胶原蛋白(Col Ⅲ)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Ⅲ型胶原蛋白(Col Ⅲ)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 Col Ⅲ. 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 Col Ⅲ 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.
