Write down the values in bold print. You are isolating a protein with a pl of 8.5 using cation exchange chromatography. You add your protein to the column in a solution at pH of 3 and collect the eluant as fraction A. You then wash the column with a buffer at pH 5 and collect the eluant as fraction B. You do a third wash of your column with buffer at pH of 7 and collect the eluant as fraction C. You do a fourth and final wash of the column with buffer at pH 12 and collect the eluant as fraction D. Which fraction contains most of your protein? O Fraction A O Fraction B O Fraction C O Fraction D O None of the above O All of the above
