For the Bradford assay, the response (absorbance per unit concentration) of the unmodified and reductively methylated proteins were similar with a slight decrease in the response upon methylation. -1-propanesulfonic acid (DSS) were purchased from Sigma Aldrich. The BCA assay kit and Coomassie Plus (Bradford) assay reagent were purchased Since publication of the initial Bradford assay [1], there have been several modifications [2], [3], while many commercial kits have been also developed.An alternative assay for protein quantification of equally wide use is the Lowry method [4], [5], commercialized as BCA kits by Sigma, Pierce and BioRad.We have previously proposed the binding mechanism of Coomassie Brilliant Blue G-250 (CBB 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 μ. 0.1 ml of the protein sample and 3 ml of the Bradford Reagent per tube. It is possible to do an assay directly in a cuvette by adding just 1.5 ml of Bradford Reagent to 0.05 ml of sample. Note: It is necessary to create a standard curve during each assay, regardless of the format used. 1.
