Purification and characterization of CPV VP2 proteins and VLPs.
(A) SDS–PAGE of His–SUMO–VP2 proteins cleaved with enzyme (Lane 2, VP2 protein) or without enzyme (Lane 1, His-SUMO-VP2). (B) Western blot of His–SUMO–VP2 proteins cleaved with enzyme (Lane 2, VP2 protein) or without enzyme (Lane 1, His–SUMO–VP2). (C) TEM image of CPV VLPs. (D) Fluorescence spectra of VP2 and VLPs in PBS solution.
