161-0326-MSDS Polypeptide SDS-PAGE Standards English

The polypeptide SDS-PAGE standards are a mixture of six proteins (1.4–26.6 kD), including six reference bands (1.4, 3.4, 6.5, 14.4, 16.9, 26.6 kD). Blended to give uniform band intensities when stained with Coomassie G-250 or zinc stain.

Applications and Uses

Choose polypeptide SDS-PAGE standards standards for:

  • Molecular weight estimation of polypeptides and small proteins on SDS-PAGE gels
