HSV-1 gG (residues 84-175) protein.Recombinant HSV-1 gG contains the immunodominantregions of glycoprotein G, amino acids 84-175.HSV-1-gG is purified by proprietary chromatographictechniques.Glycoprotein G-1, a viral envelope glycoproteinthat was suggested to contribute to viral entry throughapical surfaces of polarized cells, has been utilized as aprototype antigen for HSV-1 type-specific diagnosis dueto lack of cross-reactivity with its counterpart in HSV-2,gG-2.Herpes simplex virus type 1 encodes 11 envelopeglycoproteins, of which glycoprotein G-1 inducesa type-specific antibody response.
