The cloning, sequencing and expression of a major antigenic region from the feline calicivirus capsid protein.
RNA purified from the feline calicivirus (FCV) F9 vaccine strain was used to prepare a cDNA library in the expression vector lambda gt11. The library was screened for expression of FCV antigen using a rabbit antiserum prepared against purified FCV. A 330 bp cDNA clone was identified and used as a probe to obtain a larger overlapping clone of 1369 bp. Comparative sequence analysis with the CFI a...
متن کاملFeline calicivirus capsid protein expression and capsid assembly in cultured feline cells.
The capsid protein of feline calicivirus (FCV) was expressed by using plasmids containing cytomegalovirus, simian virus 40, or T7 promoters. The strongest expression was achieved with the T7 promoter and coinfection with vaccinia virus expressing the T7 RNA polymerase (MVA/T7pol). The FCV precursor capsid protein was processed to the mature-size protein, and these proteins were assembled in to ...
متن کاملAnalysis of feline calicivirus capsid protein genes: identification of variable antigenic determinant regions of the protein.
Three isolates of feline calicivirus (FCV) designated NADC, KCD and CFI/68 were compared for biochemical, serological and genetic variation within the capsid protein gene. The M(r) of the capsid protein from purified virions was approximately 66,000 for the NADC virus isolate, which differed slightly from the relative mobilities of the purified capsid proteins of the KCD and CFI/68 isolates. Po...
متن کاملLocation of monoclonal antibody binding sites in the capsid protein of feline calicivirus.
We report the localization of three monoclonal antibody (MAb) binding sites in the capsid protein of feline calicivirus. Gene fragments were generated by restriction enzyme digestion or the polymerase chain reaction, and expressed as beta-galactosidase fusion proteins in Escherichia coli. These chimeric molecules were screened using three MAbs. A non-neutralizing MAb recognized a region within ...
متن کاملMapping of antigenic sites involved in neutralization on the capsid protein of feline calicivirus.
In order to locate amino acid residues involved in the formation of feline calicivirus (FCV) neutralizing epitopes, we analysed the capsid protein gene of monoclonal antibody neutralization-resistant variants of FCV. Amino acid substitutions in the variants were identified in the two hypervariable regions of the capsid protein. Four linear and two conformational epitopes were located in the reg...
