Recombinant rHSV-2 gD Antigen may be used in ELISA and Western blots, excellent for detection of HSV with minimal specificity problems.
The E.coli derived recombinant protein contains the HSV-2 gD immunodominant regions 266-394 amino acids, fused with 26 kDa GST-tag. HSV-2-gD is purified by proprietary chromatographic techniques.
Background: Glycoprotein D (gD) is essential for replication in cultured cells. Deletion mutants of the virus for the gD gene cannot penetrate into cells and neutralizing antibodies against the glycoprotein inhibit virus entry. Studies with antibodies raised against HSV gD indicate that the glycoprotein plays a role in the cell-to-cell fusion process.
Specificity: Immunoreactive with sera of HSV-infected individuals.
