You Searched For: Protein Assays

Accurately quantifying total protein concentration is a key to most experiments and is often necessary for isolation, separation, and analysis of proteins by biochemical methods. When it is necessary to determine the total protein concentration in a sample, one of the first factors to consider is the selection of a protein assay method. These choices are typically based upon the compatibility of the method with the samples to be assayed. Each method has its own advantages and disadvantages.

Compat-Able™ BCA™ Protein assay kit

Catalog Number: (PIER23229)
Supplier: Thermo Fisher Scientific
Description: 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. The procedure is accomplished in less than 10 min with just a few simple steps. The Compat-Able™ Preparation Set is available conveniently bundled with the Pierce BCA™ Protein Assay Kit.

Solid phase biotinylation kits, EZ-Link™, Pierce™

Supplier: Thermo Fisher Scientific
Description: This antibody labeling system uses nickel chelated agarose to temporarily immobilise antibody molecules via their histidine-rich Fc regions. Once held in place on the gel, the antibody can be biotinylated at either sulfhydryl groups (after mild reduction or disulfide bonds) or primary amines. Excess labeling reagent and by-products are then washed away before recovering the labeled and purified antibody from the gel using a mild imidazole solution. No gel filtration or dialysis are needed.
