![Fig. 2. Tyrosine phosphorylation of EPR in normal and PV ECFC. Day-8 cells or FVA cells were incubated with rhEP (20 U/mL in [A] and 50 U/mL in [B]) or medium for 10 minutes (A) or 20 minutes (B) at 37°C before lysis. Human cell lysates were immunoprecipitated with anti-pTyr antibody, whereas FVA cell lysates were immunoprecipitated with antimurine EP receptor antibody. Immunoprecipitates were separated by 8% SDS-PAGE and immunoblotted with anti-pTyr antibody (A) or anti-EPR (B).
