C端端肽(CTX),也被称为羧基端胶原交联,是纤维状胶原的C端端肽,如I型和II型胶原。CTX为细胞外基质中成熟的胶原纤维降解产物。它有多种形式,其中常用的 β-CTX进入血液后不被降解,由肾脏直接排出,也被用作血清中的生物标志物,以测量骨的周转率。用于检测 CTX 标志物的测试称为血清 CrossLaps,它比目前可用的任何其他测试都对骨吸收更具特异性。 本试剂盒采用竞争法酶联免疫吸附试验(ELISA)。往预先包被有牛Ⅰ型胶原交联羧基端肽(CTXⅠ)抗原的微孔中,依次加入样本、标准品、Biotin标记的抗体,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牛Ⅰ型胶原交联羧基端肽(CTXⅠ)呈负相关。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 competitive enzyme-linked immunosorbent assay (ELISA) principle. Microplate wells are pre-coated with Bovine CTXⅠ antigen. The sample, standards, a biotin-labeled antibody, and an HRP enzyme conjugate are then added sequentially to the wells. The procedure includes incubation and wash steps between each addition. TMB substrate is used for color development. In the presence of the peroxidase (HRP) enzyme, TMB is catalyzed to produce a blue color, which is then converted into a final stable yellow color upon the addition of an acid stop solution. The intensity of the resulting yellow color is inversely proportional to the concentration of Bovine CTXⅠ in the sample. The optical density (OD) is measured at a wavelength of 450 nm using a microplate reader, and the concentration of the target analyte in the sample is calculated based on the standard curve.
