Production of Polyclonal Antibodies to a Recombinant Coat Protein of <i>Potato mop‐top virus</i>

Abstract

Abstract The coat protein (CP) coding regions of two Czech Potato mop‐top virus (PMTV) isolates were sequenced and shown to be identical. One, the Korneta isolate CP gene, was cloned in several expression vectors. The recombinant PMTV‐CP was expressed in Escherichia coli and the purified recombinant protein was used to produce PMTV‐specific polyclonal antibodies. The antiserum had a titre of 1 : 2000 in an indirect enzyme‐linked immunosorbent assay (ELISA) and reacted specifically in immunoblotting and IPTA‐ ELISA (indirect plate‐trapped antigen (PTA)‐ELISA).
