Comparison of the activities of mOSM-RFP and a mOSM-neutralizing antibody. MEF were stimulated for 20 min with 5 ng/ml mOSM in the presence of (A) mOSM-RFP or (B) a neutralizing polyclonal mOSM antibody at varying concentrations as indicated. Cellular lysates were analyzed for tyrosine phosphorylation of STAT3 and total STAT3 by Western blotting. GAPDH was detected as another loading control.
