rec. HIV-II antigen (rHIV-II) 100 µg

Lyophilized after extensive dialysis against 5 mM phosphate buffer pH=7.3 containing 0.01% SDS.

This antigen is an E.coli-derived recombinant protein that composes all of the reported immunogenic determinants found in gp39. The gene encoding this fusion protein was synthesized using codons optimized for E.coli expression and doesn’t represent a linear HIV-II envelope sequence. rHIV-II is a non-glycosylated, polypeptide chain, having a molecular mass of 16,127 Dalton. rHIV-II is purified by standard chromatographic techniques. This antigen was thoroµghly tested in various tests as well as ELISA using the standard BBI serum panels & 3 gp39-specific monoclonal antibodies. All antibody detection tests on this antigen were as sensitive or more than the standard Abott third generation tests.
