RESUMO

Nucleotide sequence and mRNA localization studies have allowed the prediction of the amino acid sequence of herpes simplex virus type 1 (HSV-1) glycoprotein C (gC). We immunized a rabbit with a conjugate of bovine serum albumin and a synthetic peptide having the same sequence as that deduced for amino acids 128 through 139 of HSV-1 gC. A very similar amino acid sequence has been predicted to exist in the related product, herpes simplex virus type 2 (HSV-2) gC, which was formerly designated gF. Preparations of crude antiserum and immunoaffinity-purified antibodies were obtained and shown to react in enzyme-linked immunosorbent assays with purified HSV-1 gC and HSV-2 gC. Although these antibodies did not detectably immunoprecipitate proteins from radiolabeled infected cell extracts, they reacted with HSV-1 gC and HSV-2 gC that were electrophoretically transferred to nitrocellulose membranes from polyacrylamide gels. These results confirm that HSV-1 gC and HSV-2 gC are immunologically related and also define a specific portion of HSV-1 gC that is conserved.
