WebThe Bradford protein assay is based on the observation that the absorbance maximum for an acidic solution of Coomassie Brilliant Blue G-250 shifts from 465 to 595 nm … WebThis procedure is used to measure protein concentration in samples extracted for glomalin. This assay does not give the most accurate glomalin concentration, because it is not specific for glomalin and will measure any protein (>3000 daltons) in the extract solution. The dye also reacts with polyphenolics which may be co-extracted with glomali...

WebJun 1, 2016 · Detailed in this appendix are some commonly used methods for protein analysis, e.g., Lowry, Bradford, bicinchoninic acid (BCA), UV spectroscopic, and 3-(4-carboxybenzoyl)quinoline-2-carboxaldehyde (CBQCA) assays. The primary focus of this report is assay selection, emphasizing sample and buffer compatibility. WebPerform a Bradford assay, a Lowry assay or a bicinchoninic acid (BCA) assay. Bovine serum albumin (BSA) is a frequently used protein standard. Once you have determined the concentration of each sample, you can freeze them at -20°C or -80°C for later use or prepare for immunoprecipitation or for loading onto a gel.
The Bradford protein assay was developed by Marion M. Bradford in 1976. It is a quick and accurate spectroscopic analytical procedure used to measure the concentration of protein in a solution. The reaction is dependent on the amino acid composition of the measured proteins.
