Recombinant glycoprotein G analog for determination of specific immunoglobulins to herpes simplex virus type 2 by ELISA.

In order to the detection of type-specific IgG to herpes simplex virus type 2 (HSV-2) in human serum or plasma the recombinant analog of HSV-2 glycoprotein G (gG2) was created. To construct an expression vector the DNA fragment with a sequence identical to immunodominant regions of HSV-2 gG2 was cloned into modified vector pET28a containing of the glutation-S-transferase sequence (pET28-GST). Escherichia coli BL21 (DE3) were transformed with the recombinant plasmid.
