Analysis of S protein expression and incorporation into pseudovirus. (A) Western blot analysis. S proteins expressed in transfected 293T cells were probed with MAb F26G8 or S-MAb (top); the middle and bottom panels are Western blots of pelleted pseudoviruses using MAbs F26G8 and p24, respectively. (B) EM examination of pseudovirus morphology. The name of the S protein construct in each pseudovirus is shown at the top left corner of the electron micrograph.
