Protein Electrophoresis & Western Blotting

Protein electrophoresis and Western blotting are critical methods for protein resolution and protein detection and analysis, respectively. We offer a wide variety of standard buffers, reagents, and stains for Western blotting. Our blocking, transfer, and wash buffers are all available in a variety of concentrations and package sizes. Choose from gel casting reagents or pre-cast gels, to simplify your protein resolution. Immobilon® PVDF membranes are the ideal transfer membranes for protein blotting applications.
