产品介绍

核酸多肽蛋白标记 SunRed SE是美国AAT Bioquest生产的核酸染料。虽然磺酰罗丹明101酰氯(也称为TexasRed®)是最常用的磺酰氯标记试剂,但它在水中非常不稳定,特别是在pH较高与脂族胺反应时。此外,与染料琥珀酰亚胺酯相比,TexasRed的标记效率极低。 SunRed SE是一种琥珀酰亚胺酯。它是Texas Red的绝佳替代品。 SunRed与胺化合物(如氨基酸,肽和蛋白质)发生反应,得到非常稳定的亮红色荧光缀合物。与TexasRed相比,SunRed具有更高的标记效率,更重要的是,所得到的缀合物比相应的TexasRed缀合物荧光和水溶性更好。 SunRed的缀合物具有与TexasRed®相同的激发和发射波长。经研究表明,在相同的标记条件下,SunRed比TexasRed更稳定。它对于标记疏水性肽非常有用,使得荧光缀合物更易于纯化并且更易溶于水。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的核酸多肽蛋白标记 SunRed SE。
