Bradford assay principle and procedure
WebApr 12, 2010 · It is shown that under standard assay conditions, the ratio of the absorbance measurements at 590 nm and 450 nm is strictly linear with protein concentration. This simple procedure increases the accuracy and improves the sensitivity of the assay about 10-fold, permitting quantification down to 50 ng of bovine serum albumin. WebNov 12, 2024 · The Bradford Protein Assay is a simple spectroscopic technique which is used in laboratory research to measure the total concentration of protein in a particular sample. The principle of the procedure revolves around the concept that the maximum absorbance of acidic Coomassie Brilliant Blue G-250 alters when protein binding occurs.
