Isolation and purification of HSV-1 specific transfer factor produced by HSV-1 immunized goat leukocyte dialysate.
A herpes simplex virus type 1 (HSV-1)-specific transfer factor (TF), was separated and purified from the leukocyte dialysate of goats immunized with HSV-1 using affinity chromatography on antigen-sorbent and reversed phase high performance liquid chromatography (RP-HPLC). The antigen-specific activities of the starting dialysate and the isolated TF component (s) were examined by 51Cr-labelled leukocyte adherence inhibition (51Cr LAI) assay. The analytical hydrophobic interaction HPLC (HI-HPLC) and isoelectric focusing (IEF) techniques were employed to evaluate the purity and the isoelectric point (PI) of isolated TF component(s). The experiments provided a two-step procedure for purifying the TF material from the starting dialysate. It seems that the purified active TF component (PTFC) was specific for HSV-1. The specific PTFC activity was increased 10,000-fold as compared with the activity of the dialysate. The active moiety appeared as a single band in the IEF gel as demonstrated by silver staining; it was hydrophilic and its PI was pH 4.48.
