Please complete Table 2 and show the calculations for protein concentration and the concentration of the undiluted sample.  a). Using Excel software, enter data from Table 1 to plot a standard curve (corrected average absorbance on Y-axis and protein concentrations on X-axis). The standard curve must contain correct labels on both axes. b). From the standard curve, obtain a best fit line and equation. c). Use the best fit equation and data from Table 2 to find the concentrations of proteins in sample A2-D2 and E1.  [onto your plotted standard curve, indicate where A595 of A2-D2 and E1 are located]  d). Calculate the concentrations of proteins in undiluted samples A to E. Thank you very much.

Please complete Table 2 and show the calculations for protein concentration and the concentration of the undiluted sample. 

a). Using Excel software, enter data from Table 1 to plot a standard curve (corrected average absorbance on Y-axis and protein concentrations on X-axis). The standard curve must contain correct labels on both axes.

b). From the standard curve, obtain a best fit line and equation.

c). Use the best fit equation and data from Table 2 to find the concentrations of proteins in sample A2-D2 and E1.  [onto your plotted standard curve, indicate where A595 of A2-D2 and E1 are located] 

d). Calculate the concentrations of proteins in undiluted samples A to E.

Thank you very much.
