Figure Lengend Snippet: Immunoblotting with antiribosomal P proteins. (A) Identification of the cellular ribosomal P proteins (proteins of the 60S subunit of the ribosome) by Western blot using human antiribosomal P protein antiserum. P0 is 38 kDa, P1 is 19 kDa, and P2 is 17 kDa. Ribosomes purified from 293T cells were used as positive control (lanes 1 to 3, i.e., 250, 100, and 50 ng of proteins, respectively). An equal amount of virions is loaded on each lane, as determined by MuLV Gag or CA quantification by immunoblot using a p30CA antiserum (example in panel B). Lane 4, PR− MuLV; lane 5, C17−; and lane 6, C37−. Lanes 8 and 11, MuLV wild type; lane 9, NC(Δ16-23); and lane 12, C39S. The mock preparations correspond to the same volume of culture media as for C37− (lane 7) or NC(Δ16-23) virions (lane 10). wt, wild type. (B) Western blot of several samples used in panel A, probed with a p30CA antiserum. Lane M, protein molecular weight marker RPN756 (Amersham Pharmacia) (in kilodaltons). Lane 1, wild-type MuLV; lanes 2, 3, and 4 are PR−, C17−, and C37− mutants, respectively.
