沉默调节蛋白3(SIRT3)是一种由SIRT3基因[sirtuin(沉默交配型信息调节2同源物)3(S. cerevisiae)编码的蛋白质。它是一个位于线粒体基质中的可溶性蛋白,在N端含有一个线粒体处理肽。一组SIRT3的晶体结构已经被解决,包括一个没有底物的apo结构,一个含有其天然底物乙酰CoA合成酶2的乙酰赖氨酸的肽的结构,一个被硫代乙酰肽困住的反应中间结构和一个含有脱硫代乙酰肽键的结构。这些结构显示了反应所需的两个底物--乙酰化底物肽和NAD+所引起的构象变化。乙酰化肽是与它结合的第一个底物,在NAD+之前。 本试剂盒采用双抗体夹心法酶联免疫吸附试验(ELISA)。往预先包被有大鼠沉默调节蛋白3(SIRT3)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大鼠沉默调节蛋白3(SIRT3)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 Rat SIRT3. 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 Rat SIRT3 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.
