Brightein Protein Gel Stain,10

蛋白电泳
  Brightein 蛋 白 凝 胶 染 色 液 是 用 于 检 测 SDS Polyacrylamide Gel(SDS-PAGE)中蛋白的发光染料。该染 料与 SYPRO Ruby 染料有许多相同的特征,例如有着检测 1ng 或更少蛋白的灵敏性,可用 UV 和可见光激发的兼容性, 出色的光稳定性和至少 3 个数量级的线性检测范围。但是 Brightein 比 SYPRO Ruby 还有另外一些重要的优势。使用 Brightein 蛋白染色比 SYPRO Ruby 更简单和快速,只需 90 min 孵育就能完成固定和染色蛋白步骤;随后,染色的凝胶 可立即成像,或在成像之前进行简单的脱色、水洗。Brightein 蛋白定量的线性度至少可延长三个对数单位,但是与 SYPRO Ruby 相比,Brightein 染色的线性图具有更小的斜率。 因此,高浓度的蛋白在 SYPRO Ruby 染色凝胶中可能比 Brightein 更亮,然而,低浓度的蛋白在 Brightein 染色凝胶 中通常比 SYPRO Ruby 更亮。这种斜率差异使 Brightein 染 色对双向电泳凝胶很有利,因为低浓度蛋白的荧光斑点不容 易被附近高浓度的蛋白荧光所压制。最后,Brightein 蛋白凝 胶染色与下游蛋白分析(如质谱法和基于 Edman 的测序) 完全兼容,而且样品制备方法与 SYPRO Ruby 凝胶染色相 同。
