Ponceau 2R, Xylidine ponceau, Ponceau G, Red R, Acid Red 26, Food Red 5, or C.I. 16150 is a red azo dye used in histology for staining. It is easily soluble in water and slightly in ethanol. It usually comes as a disodium salt.

针对上述问题有人提出了一些解决方法，例如使用丽春红染色（Ponceau staining）或考马斯亮蓝染色（Coomassie staining）替代β-Actin进行数据标准化。 当然也有文献这么做，例如：

考马斯亮蓝染色液有G250和R250两种，R代表red，与蛋白结合后呈红色或粉红色；G代表green，与蛋白结合后呈蓝绿色。 具有容易检测、灵敏度高（最低可检测50ng的蛋白）的特点，常用于SDS-PAGE或非变性PAGE蛋白凝胶的染色，也被用于 Western转膜 后PAGE胶上残余蛋白的 ...

Ponceau (French for "poppy-colored") may refer to: Ponceau 2R (also called Xylidine ponceau or Ponceau G, among other synonyms), azo dye used in histology for staining; Ponceau 3R, delisted food colorant; Ponceau 4R (known by more than 100 synonyms), synthetic colourant used as a food colouring (E Number E124)
