Make a Beer’s Law standard calibration plot by plotting the average absorbance vs. concentration. Use the concentration as calculated in question 2. Follow the instructions for making plots as outlined in the lab manual introduction. (6 points) a. Fit the data with a straight line. If the data extend beyond the linear range, do not include the non- linear points. b. Use the standard deviations to include error bars on your absorption measurements. c. Staple your plot to the back of this report. 4. Use the plot to determine the extinction coefficient (ε) for the CBBG- BSA complex. (Note: Typically, the molar extinction coefficient is reported in units of M- 1 cm- 1. Since you don’t have the molar mass of BSA, you will report the extinction coefficient in units of mL...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
