Thermo Scientific Spectra 多色低分子量蛋白分子量标准是六种蛋白和合成肽(1.7 至 40 kDa)的混合物,可用作凝胶电泳和蛋白免疫印迹中肽和小分子蛋白的分子量标准品。蛋白标准品以即用型规格提供,用于直接上样至凝胶;使用前无需加热、还原或添加样品缓冲液。应用• 在 SDS-PAGE 期间监测蛋白迁移• 验证 Western 转印效率• 近似测定 SDS-聚丙烯酰胺凝胶和 Western 印迹上的蛋白大小• 定位用于从未染色制备凝胶中切除的目标蛋白

数据:

Migration patterns of Spectra Multicolor Low Range Protein Ladder in different electrophoretic conditionsThe apparent molecular weight of each protein (kDa) has been determined by calibration of each protein against an unstained protein ladder in specific electrophoresis conditions. Migration patterns were determined using commercial precast mini gels. SP refers to small peptide SDS-polyacrylamide gels with a higher degree of crosslinking (c=5% instead of usual ~3%).

SDS-PAGE band profile of the Spectra Multicolor Low Range Protein LadderImages are from an 18% Tris-tricine small-peptide SDS-polyacrylamide gel with 5% crosslinking, and subsequent transfer to membrane.
