Fast isolation of recombinant baculovirus by antibody screening

We describe a rapid and efficient scheme for the isolation and purification of recombinant baculoviruses. The method is based on the detection of foreign proteins in cellular lysates of baculovirus-infected insect cells by antibody screening. The recombinant virus is purified by repeated serial dilutions. The method allows the identification and purification of recombinant viruses within 2 to 3 wk. This procedure selects for recombinant baculoviruses that highly overproduce the desired protein product.
