Please would somebody help me to solve the following exercise: Determine the protein concentrations of the four unknown samples (A,B,C,D) using the raw data obtained from a Bradford assay.
Absorbance values at 595 nm for the BSA known samples and unknown samples are available. 40 μL of each protein sample was mixed with 2.96 mL of Bradford reagent.
Sample Absorbance @ 595nm
A 0.085
B 0.001
C 1.300
D 0.150
BSA mcg/ml AU 595nm
30 0.04
50 0.05
70 0.09
90 0.11
110 0.14
130 0.17
