Glycoproteins of nuclear polyhedrosis viruses

The glycopeptides and glycoproteins of two nuclear polyhedrosis viruses (NPVs) grown in two lepidopteran insect cell lines were studied using Sephadex elution chromatography and polyacrylamide gel electrophoresis. No quantitative or qualitative differences were observed in the glycopeptide and glycoprotein patterns between the viruses grown in either cell line. However, both viruses synthesized a glycoprotein which was not observed in either insect cell line and may be virus-directed.
