产品介绍
酪酰胺信号放大 (TSA,Tyramide signal amplification) 技术是一类利用辣根过氧化酶(HRP)对靶蛋白进行标记的酶学检测方法,类似常规免疫组化的DAB显色方法,TSA技术同样采用HRP标记的二抗,同样有对应的“显色”步骤(HRP催化加入反应体系的酪胺荧光素底物,产生活化荧光底物,活化底物可与抗原上的酪氨酸等残基共价结合,使样品上稳定的共价结合酪胺荧光素。之后用热修复法或者抗体洗脱液洗去非共价结合的一抗-二抗-HRP复合物,重复下一种一抗-HRP二抗来第二轮孵育,换另一种酪胺荧光素底物,如此往复就可实现多重标记。 TSA详细原理是利用酪胺Tyramide的过氧化物酶反应(酪胺盐在HRP催化H₂O₂下形成共价键结合位点),产生大量的酶促产物,该产物能与周围的蛋白残基(包括色氨酸、组氨酸和酪氨酸残基)结合,这样在抗原-抗体结合部位就有大量的荧光素沉积,结果使其检测信号得到10-100倍增强。简单来说,用这种方法做多重免疫荧光是利用二抗上带有的HRP(而不是直接偶联荧光素),来催化后续添加入体系的非活性荧光素。荧光素在HRP和过氧化氢的作用下被活化,跟临近蛋白的酪氨酸残基共价偶联,使得蛋白样品与荧光素稳定结合。然后微波或煮沸或者水浴等热修复处理,前一轮非共价结合的抗体被洗掉,共价结合的荧光素稳定共价结合在样本切片蛋白上。再换个一抗来第二轮孵育,周而复始。等到所有抗体孵育结束,荧光素都结合好后,最后去检测结果。由于每次体系中都只有单一抗体孵育,因此无需担心抗体交叉反应,以及一抗二抗种属匹配问题,大大减少了实验设计时不同种属抗体选择匹配的限制。也就是说,如果用TSA技术,同一张片子上所有的靶标都可以选用特异性高的兔单克隆抗体。搭配同一支抗兔的HRP二抗就可以进行实验,而且信号放大的倍数大大增强。本公司开发的试剂盒具体酪胺荧光染料为以下其中一种或者多种:TYR-480,TYR-520,TYR-570,TYR-620,TYR-690,TYR-780。此试剂盒中的荧光染料可单独或配合使用。可以实现单标、双标、三标以及更多重荧光放大/多重同源抗体荧光标记等功能,极大丰富了此试剂盒的内涵。 试剂盒组成: C1372339
