组织蛋白酶K(Cathepsin K),缩写为CTSK,是一种在人类中由CTSK基因编码的酶。该基因所编码的蛋白是一种溶酶体半胱氨酸蛋白酶,参与骨重塑和吸收。该蛋白是肽酶C1蛋白家族的成员,主要在破骨细胞中表达。Cathepsin K是一种蛋白酶,它的定义是对激肽的高度特异性,参与骨吸收。该酶分解弹性蛋白、胶原蛋白和明胶的能力使其能够分解骨和软骨。这种分解代谢活动也是肺气肿中肺部弹性和反冲力丧失的部分原因。白蛋白酶K抑制剂在治疗骨质疏松症方面显示出巨大潜力。白蛋白酶K被白蛋白酶S降解,这一过程被称为受控白蛋白酶食人。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人组织蛋白酶K(Cath-K)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组织蛋白酶K(Cath-K)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 Cath-K. 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 Cath-K 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.
