Protein Gel Electrophoresis Information

Learn about methods and technologies for separation and analysis of proteins by polyacrylamide gel electrophoresis (PAGE). Understand gel types (pouring, precast, gradient, 1D, 2D, etc.), gel and running buffer systems, sample preparation and loading, molecular weight markers (protein ladders), and gel stains.

Protein gel electrophoresis learning resources


This 88-page handbook provides detailed description about all aspects of protein electrophoresis from sample and gel preparation to choice of molecular weight markers. In addition, it contains extensive information about our portfolio of high-quality protein electrophoresis products including gels, stains, molecular weight markers, running buffers, and blotting products for your experiments.

Application note

The Thermo Scientific Pierce Power Stainer is an easy-to-use device for rapid electrophoretic Coomassie staining and destaining of protein gels, typically in 6–11 minutes, with staining performance equivalent to or better than traditional solution-based Coomassie staining.
