External markers and method for the identification of protein-and-peptide-containing samples utilizing capillary electrophoresis analysis. As disclosed, at least two external markers are added to the sample: one of the markers is a neutral charge species and one of the markers is an ionic species. Dimethylformamide is a preferred neutral charge species and benzoic acid is a preferred ionic species. Identification of constituent species is determined by comparing the migration ratios of the constituent species with migration ratios for each constituent species member.
利用毛细管电泳分析鉴定含蛋白质和肽样品的外部标记物和方法。正如所披露的,样品中至少添加了两种外部标记物:其中一种标记物为中性电荷,另一种标记物为离子性电荷。二甲基甲酰胺是首选的中性电荷种类,苯甲酸是首选的离子种类。通过比较组成物种的迁移比率和每个组成物种成员的迁移比率,确定组成物种。
