SDS-PAGE on peanut protein from Mt Sinai
Ran SDS-PAGE with Bert to gauge purity/protein concentration of Ara h 2, Ara h 3, and Ara h 6 stock from Mt Sinai, each with a stated concentration of 3 mg/ml. Ran nanodrop to determine true (approximate) protein concentrations: Ara h 2: ~1 mg/ml Ara h 3: ~2 mg/ml Ara h 6: ~0.5 mg/ml For SDS-PAGE, we want to create a loading solution for each protein at a concentration of 0.5 µg/µl. Loading solution composition: Loaded the gel w/ 1 µg and 5 µg for each protein. Gel According to Bert, band sizes, when matched to bands of known protein concentration (from his past gels), reflected nanodrop concentrations fairly well.
