Tenascin X(TN-X)是Tenascin家族的一个成员,也被称为hexabrachion样蛋白,是一种糖蛋白,在结缔组织包括皮肤、关节和肌肉中表达。tenascin X是由TNXB基因编码的。该基因定位在6号染色体上的主要组织相容性复合体(MHC III类)区域。该基因的结构是不寻常的,因为它的5'和3'端分别与CREBL1和CYP21A2基因重叠。该基因编码的是细胞外基质糖蛋白tenascin家族的一个成员。Tenascins具有抗粘连的作用,而纤维蛋白则具有粘连性。该蛋白被认为在伤口愈合过程中起到基质成熟的作用。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有人肌腱蛋白X(TNX)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肌腱蛋白X(TNX)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 TNX. 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 TNX 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.
