Quantitation of submicrogram quantities of protein by an improved protein-dye binding assay

Biochim Biophys Acta. 1978 Apr 26;533(2):525-9. doi: 10.1016/0005-2795(78)90398-7.

Abstract

A quantitative assay method for protein is described which is based on the color change occurring in Coomassie Brilliant Blue G-250 when it binds to protein. This modification of two similar procedures further increases the sensitivity, simplicity, and stability of the protein-dye binding assay over those of other commonly used assays for protein.
