The Thermo Scientific™ Compat-Able™ Coomassie Plus Protein Assay Kit eliminates interfering substances from protein assay samples to make them compatible with BCA and Bradford assays.

• Eliminate incompatibilities — removes nearly any substance that interferes with colorimetric protein assays: salts, detergents, denaturants, reducing agents, and even IEF sample buffer
• Simple and fast — prepare samples in less than ten minutes with four simple steps
• Convenient — reagent set is easier to use than homemade TCA or acetone precipitation reagents, thereby producing more consistent results
• Scalable — microcentrifuge method is easily scaled to larger centrifuge tube volumes for special needs
• Validated — tested and offered together with BCA and Coomassie Plus Protein Assay Kits; protocol integrates control and normalisation procedures

The Compat-Able™ reagents remove salts, detergents, reducing agents and other substances from protein samples to eliminate interference with protein assays. The protocol selectively precipitates all of the protein, thereby allowing the non-protein components to be easily decanted and removed. The purified, precipitated protein is redissolved in water, making it ready for accurate determination of the protein concentration by standard protein assay methods.
