产品介绍

生物胞素 C2 马来酰亚胺是美国AAT Bioquest生产的生物素类荧光探针。生物胞素马来酰亚胺易与生物大分子硫羟基部分反应,形成硫醚偶联物,它十分稳定。生物胞素马来酰亚胺需要温和地结合条件。例如,在PH5.5通常是修饰半胱氨酸残基的最佳PH, 并且无论什么时候,尽量减少暴露在空气中溶液反应,尽可能避免硫羟化底物在空气中氧化。大多偶联物在室温下形成。然而,升高或者降低温度都可能需要特定的标记反应。生物胞素必须置于无外来硫醇的缓冲液中(6-巯基乙醇、二硫苏糖醇和巯基乙胺)反应。蛋白质或者多肽通过与不含有硫醇基团(SH)的试剂进行硫羟化反应形成生物胞素。金畔生物是AAT Bioquest的中国代理商,为您提供最优质的生物胞素 C2 马来酰亚胺。
