基质金属蛋白酶-2(MMP-2)也被称为72 kDa的IV型胶原蛋白酶,是一种在人类中由MMP2基因编码的酶。MMP2基因位于16号染色体上的12.2位。基质金属蛋白酶(MMP)家族的蛋白质参与正常生理过程中细胞外基质(ECM)的分解,如胚胎发育、繁殖和组织重塑,以及疾病过程,如关节炎和转移。大多数MMP是以非活性原蛋白的形式分泌的,当被细胞外蛋白酶裂解时被激活。该基因编码一种降解IV型胶原蛋白的酶,它是基底膜的主要结构成分。该酶在子宫内膜月经分解、血管调节和炎症反应中起作用。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人基质金属蛋白酶2(MMP-2)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基质金属蛋白酶2(MMP-2)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 MMP-2. 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 MMP-2 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.
