Proteomics

Our Protein Research section covers the spectrum of research products for proteomics.

There are products for Protein Purification, including Protein Extraction, Fractionation, Sample Preparation and Protein Concentration.

Our Protein Analysis products cover Protein Electrophoresis, Western Blot, and Mass Spectrometry.  A wide selection of Protein Labeling and Protein Modification tools are available for protein binding and protein structure studies.

A large selection of Protein Assays are available, including unique Protein Estimation Assays.

The Reversible Copper Stain™ is a single step stain for rapid detection of proteins resolved on SDS-PAGE. No destaining is necessary.   The stain is based on the interaction of copper ions with polyacrylamide and proteins. The stain works by depositing a copper metal precipitate in th..
