The associated files are mass spec data from two HPLC fractionations (Size Exclusion (SEC) or a triple phase ion exchange combination (WaxWaxCat)) of a single native protein extract from Selaginella moellendorfii. The extract was made from frozen powdered green tissue in 50 mM Tris pH 7.5, 150 mM NaCl, 5 mM EGTA, 10% glycerol, 1% NP40, phosphatase inhibitors and plant-specific protease inhibitors. 1 mg total protein was separated by SEC and 1.25 mg (diluted to 50 mM NaCl) by a concatenated series of three columns: PolyWaxLP, PolyWaxLP, and poly CAT A (PolyLC, Inc). The triple column series was eluted with a NaCl gradient. The ion exchange fractions # 55-60 were not processed for mass spectrometry becaue the A280 trace from the HPLC indicated insufficient protein present in those fractions.
