Overview

Natural protein standards are available in broad, low, and high MW ranges. Prestained standards allow for quick visual assessments during electrophoresis and transfer. Unstained standards are optimized for Coomassie and zinc staining.

Prestained SDS-PAGE Standards
Prestained standards for SDS-PAGE and western blotting provide a quick and easy way to monitor protein separation during electrophoresis and to assess transfer efficiency on blots.

Unstained SDS-PAGE Standards
SDS-PAGE unstained standards, available in high, low, and broad molecular weight ranges, are blended to give uniform band intensities when stained with Coomassie Blue R-250 or zinc stains.

Biotinylated Standards
Biotinylated SDS-PAGE standards have now been discontinued. Please visit our Discontinued Products overlay on the biotinylated standards page for recommended Precision Plus Protein counterparts.
