Protein Electrophoresis

A major tool in the analysis of a species' proteome is the ability to separate and visualize the proteins by electrophoresis, 1D or 2D, and then the subsequent visualization of the proteins. Electrophoresis is a quick, simple and sensitive tool for separating proteins and nucleic acids by size and/or electrical charge. G-Biosciences offers a wide selection of electrophoresis kits, reagents and accessories. The G-Biosciences’ electrophoresis range extends from sample preparation for electrophoresis to running the protein samples by 1D and 2D electrophoresis.
G-Biosciences has also developed a wide selection of electrophoresis gel stains for visualizing proteins that vary in sensitivity, staining time and reversibility.
A wide selection of buffers and chemicals for gel casting and electrophoresis are also available.
