Ⅰ型胶原蛋白（ColⅠ）是动物体内含量最多、分布最广的蛋白质，占人体胶原蛋白总量的80%以上。它主要存在于皮肤、骨骼、肌腱等结缔组织中，为组织提供机械支撑和强度。Ⅰ型胶原蛋白由两条α1链和一条α2链组成，形成三股螺旋结构，具有高度的抗拉强度。它在皮肤中占比超过80%，是维持皮肤弹性和紧致度的关键成分。随着年龄增长，Ⅰ型胶原蛋白的合成减少，导致皮肤老化、皱纹和松弛。 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Ⅰ型胶原蛋白(ColⅠ)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Ⅰ型胶原蛋白(ColⅠ)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 ColⅠ. 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 ColⅠ 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.
