Synthetic peptides to identify antigenic determinants on Epstein-Barr virus gp350/220.
We synthesized three peptides, MA1 - Thr19-Val28(+Tyr) -, MA2 - Ser807-Ala816-, and MA3-Ser718-Glu729(+Tyr) from the sequence of Epstein-Barr virus gp350/220 and immunized rabbits with these peptides. Rabbit antisera to the peptides had antipeptide radioimmunoassay titers of 1:400 for anti-MA1, 1:200 for anti-MA2, and 1:1600 for anti-MA3. The anti-MA1 serum recognized gp350/220 in Western blotting to SDS-electrophoresed proteins from 12-O-tetradecanoylphorbol-13-acetate- and n-butyrate-treated B95-8 cells, but anti-MA2 and MA3 sera did not. None of the sera reacted with gp350/220 by membrane or cytoplasmic immunofluorescence or by immunoprecipitation of Triton X-100 solubilized proteins.
