Recently, a novel porcine circovirus-like virus P1 with a circular DNA genome of 0.648 kb was identified. P1 antigen was detected both in vitro and in vivo by synthetic peptide-derived polyclonal antibody-based immunochemistry. The designed peptides were synthesized by solid-phase technique, purified by high performance liquid chromatography, coupled to Keyhole limpet hemocyanin, and injected into rabbits to prepare polyclonal antibody. The emergence of positive cells revealed that synthetic peptide could elicit antibodies against P1 and viral protein could be synthesized. The polyclonal peptide antibodies described here was successfully applied to immunochemical staining and proved helpful in diagnosing P1.
