I型胶原α1(COL1A1)也被称为α-1型胶原蛋白,是由COL1A1基因编码的蛋白质,是大多数结缔组织(包括软骨)中的纤维状胶原蛋白。胶原蛋白是一种加强和支持身体许多组织的蛋白质,包括软骨、骨骼、肌腱、皮肤和眼睛的白色部分(巩膜)。COL1A1基因产生I型胶原蛋白的一个组成部分,称为原α1(I)链。这条链与另一条原α1(I)链以及原α2(I)链(由COL1A2基因产生)结合,形成I型原生胶原蛋白分子。这些三股绳状的原生胶原蛋白分子必须由细胞外的酶进行加工。一旦这些分子被加工,它们就会排列成长而细的纤维状,在细胞周围的空间中相互交联。交联的结果是形成非常强大的成熟I型胶原蛋白纤维。 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Ⅰ型胶原α1链前体(Pro-col1a1)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Ⅰ型胶原α1链前体(Pro-col1a1)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 Pro-col1a1. 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 Pro-col1a1 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.
