Purification and characterization of vMIP-III expressed in CHO cells.
(A) vMIP-III was purified from culture supernatants of stably transfected CHO cells by cation exchange chromatography. Column washes were performed at 0.2 mol/L NaCl/20 mmol/L Tris, pH 7.2, and vMIP-III was eluted at 0.8 mol/L NaCl/20 mmol/L Tris. (B) SDS-PAGE analysis followed by Coomassie blue staining of the peak fractions shown in A. (C) vMIP-III was subjected to MALDI-MS. The 9677.08 and 9153.67 peaks correspond to full-length vMIP-III and vMIP-III, which have been truncated at the carboxy terminus, respectively.
