RED 660™ Protein Assay is a single reagent colorimetric assay that outperforms many commercial colorimetric assays, including Bradford and improved Coomassie/Bradford assays. It offers greater linearity, colour stability, and compatibility with detergents, reducing agents and other interfering agents compared to the Coomassie assays. The single, ready to use reagent allows for rapid analysis of total protein concentration and generates highly reproducible results.

The Neutralizer™ is a unique chemical that sequesters ionic detergents, including SDS, allowing the solution to be compatible with the RED 660™ Protein Assay. The Neutralizer™ can also be used with Laemmli loading buffer. Each vial is suitable for 10 ml RED 660™ Protein Assay reagent.
