Bradford protein assay graph
WebThe Bradford assay is a commonly used method for determining the concentration of protein in a solution. It is based on the principle that the absorption of light by a protein is proportional to its concentration. The assay utilizes a reagent called Coomassie Brilliant Blue G-250, which has a high affinity for binding to proteins. WebJan 7, 2001 · The Bradford protein assay (1) is one of several simple methods commonly used to determine the total protein concentration of a sample. The method is based on the proportional binding of the dye Coomassie to proteins. Within the linear range of the assay (~5-25 mcg/mL), the more protein present, the more Coomassie binds. ...

WebThe Bradford Assay Limitations - The assay measures total protein concentration, different methods must be used to identify specific proteins. - Assay is linear over a limited range. - The Coomassie dye binds specifically to arginine and hydrophobic amino acids. - The amino acid composition can alter the concentration-absorbance curve. WebOur spectrophotometer requires that we put 2 ml volume in each cuvette. A cuvette is a transparent vessel to be placed in a light path for measurement of absorbance. To get the right proportion of assay reagent to sample, we make our sample volume 0.5 ml and add 1.5 ml color reagent to each tube.
