September Updates

Hello! Exciting news!  We tried the new enzyme digestion on the purified ArsR first.  We have been able to see 2 of the 3 aspartic acid residues we are interested in analyzing.  Based on the run I did yesterday, I think we need to increase the amount of enzyme that we are using because we…

Summary and Continuing Goals

Hello Everyone, The summer research session is drawing to a close, so I’d like to give one more update about my progress and put forth some goals for the beginning of the semester.
