A) Syncytia formation by RSV-F DNA in transfected cells. 293T cells were mock transfected or transfected with pHRSVFOptA2 and visualized by light microscopy 48 hours post transfection. The arrow indicates giant multinucleated cell formation. B) Processing of RSV F in transfected cells. 293T cells were either mock transfected (lane 1), transfected with pCMV-β-gal (lane 2), transfected with pHRSVFOptA2 (lane 3), pHRSVFOptB18537 (lane 4), or infected with RSV (Long strain, MOI = 1) for 24 hours followed by metabolic labeling for 6 hours with [35S]-cysteine/methionine. Labeled cell lysates were immunoprecipitated with HRSV F specific mAbs, and immunoprecipitates were resolved by SDS-PAGE as described in methods. C) Cell surface expression of RSV F in transfected cells. 293T cells were either mock transfected or transfected with pHRSVFOptA2 for 24 hours followed by flow cytometry using HRSV F specific monoclonal antibodies as described in methods.
