Biuret assay sensitivity
Did you know?
WebBased on protein standards ranging from 0.5mg/ml to 6mg/ml, it is possible that the BCA assay is more sensitive than the Biuret assay. This is because the BCA assay is generally more sensitive than the Biuret assay, and at lower concentrations of protein, small differences in sensitivity can have a greater impact on measurement accuracy. WebThe biuret test is a chemical test used to determine the presence of peptide bonds in a …
WebProtein estimation is used in every lab involved with proteins, but which assay is the best choice. Here's an overview of the Lowry Protein Assay, Bradford Protein Assay, BCA Protein Assay, assaying by UV absorption and the Biuret Protein Assay.
