The VP2 gene of porcine parvovirus was cloned in the baculovirus system and expressed in insect cells. The resulting product was present in high yield. It self-assembled into particles which were structurally and antigenically indistinguishable from regular PPV capsids. A high degree of purity of the recombinant capsids was obtained by ammonium sulphate(More)
In this report we describe the topological mapping of neutralizing domains of canine parvovirus (CPV). We obtained 11 CPV-specific monoclonal antibodies (MAbs), six of which are neutralizing. The reactivities were as determined by ELISA and Western blot (immunoblot) analysis. VP2, the most abundant protein of the CPV capsid, seemed to contain all the(More)
VP2 is the major component of canine parvovirus (CPV) capsids. The VP2-coding gene was engineered to be expressed by a recombinant baculovirus under the control of the polyhedrin promoter. A transfer vector that contains the lacZ gene under the control of the p10 promoter was used in order to facilitate the selection of recombinants. The expressed VP2 was(More)
The baculovirus expression system was used to produce recombinant human matrilysin. Expression of promatrilysin reached a peak at 72 h post-infection. Most of the recombinant protein remained in the intracellular fraction in an insoluble form, which after renaturation was purified by S-Sepharose and Green A Dyematrex chromatography in order to remove host(More)
