General description

Bradford assay is addition of coomassie brilliant blue G-250 to protein solution. The coomassie blue dye associates with basic and aromatic amino acids, thereby causing shift in absorbance during protein determination.

Application

Bradford Reagent has been used to determine total protein concentration.

Features and Benefits

  • The reagent is ready to use. No mixing or dilution required.
  • Color development is rapid. Only a five minute incubation and then the sample is read a 595 nm.
  • Reducing sugars and reducing substances along with thiols do not interfere with this reagent.
  • Reagent is suitable for micro (1-10 μg/ml) and standard (50-1400 μg/ml) assays.
  • Can be used in microwell plate assays.
  • Inexpensive assay.

Articles

The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the ability to accurately determine these protein amounts remains a challenge. Fortunately, over the past decade, the field of proteomics has witnessed significant advances in the area of mass spectrometry. These advances, both in instrumentation and methodology, are providing researchers with sensitive assays for both identification and quantification of proteins within complex samples. This discussion will highlight some of these methodologies, namely the use of Multiple Reaction Monitoring (MRM) and Protein-AQUA.
