[Isolation and characteristics of low molecular weight recombinant peptides, representing antigenic domains in the NP protein of lymphocytic choriomeningitis virus].

High- and low-molecular recombinant peptides of LCM virus nucleoprotein, representing individual immunodominant antigenic sites, were obtained in pJC40 expressing vector and studied in solid-phase enzyme immunoassay. 2-7% proteins resultant from total cellular synthesis are recombinant peptides. Comparative analysis of antigenic properties of recombinant peptides and native viral protein showed that recombinant peptides are virtually not inferior to native viral protein in antigenic properties.
