H-DARPin and F incorporation into HER2/neu targeting vectors. Western Blot analysis of the indicated LVs. Particle amounts loaded onto 10% sodium dodecyl sulfate–polyacrylamide gels were equivalent to 30 ng of p24 for each vector type. Proteins were detected utilizing anti-F, anti-H, or anti-p24 antibodies. Vector particles pseudotyped with unmodified or mutated H-protein (MV–LV, MVmut-LV) were used as controls.
