PURIFICATION AND CHARACTERIZATION OF ANTIVIRAL PROTEIN FROM SILKWORM FECAL MATTER

Antiviral proteins (AVP), present in silkworm fecal matter, show activity against nuclear polyhedrosis virus (NPV) in vitro and in vivo. The extract of silkworm fecal matter prepared in phosphate buffer solution of pH 7.5 was subjected to 50% solid ammonium sulfate precipitation to enrich AVP, then which was dialyzed. The dialysate was applied to the column containing silica gel-G, the column elutes were purified by gelfiltration chromatography....
