Is absorbance the same for protein (bsa) curve per unit mass
Is absorbance the same for protein (bsa) curve per unit mass
Homework Answers
Answer=
The absorbance is not same for protein (bsa) curve per unit mass.
explanation- The absorbance of bsa i.e. bovine serum albumin shows at 550 nm.
As the mass per unit BSA increases,the absorbance also increases.
because the concentration of protein i.e. bsa increases.
When we plot the curve of absorbance versus concentration of BSA we get a straight line .

1. You have generated the following standard curve after a Bradford Assay to measure Absorbance vs samples of known BSA concentrations. Now you need to determine the amount of protein in two mitochondria samples taken from fish, one taken from fish under normal conditions and the other taken from fish under oxidative stress. The absorbance reading for the normal fish fraction was A595=175, and the absorbance reading for the stressed fish fraction was A595= 275 Bradford Assay Standard Curve y...

In biochemistry, we use a 'Bradford Assay' to calculate the concentration of protein in a sample. This method uses the same principles of the standard curve from this experiment. In a Bradford Assay, a standard curve is prepared using a known protein, typically Bovine Serum Albumin (BSA), but rather than measuring the density, we can measure a different property - its 'absorbance'. The graph below is representative of a standard curve from a Bradford Assay (with the line equation displayed...
