2. Compare the abundance of A28o chromophores (W, Y, and C) to Bradford sites (loosely R and K) in BSA. 3. We used a protocol that corrects the path length in each well and normalizes the absorbance to the value that would be obtained if the path length were 1cm (the standard path length). Using this observation and your A280 calibration data, what is your measured 280 for BSA
