Novartis AG (Basel, Switzerland) has patented BIV constructs encompassing BIV combination vectors, BIV vectors and BIV packaging vectors and particularly the invention pertains to a three vector system comprising: a) a BIV vector construct including a DNA segment from a BIV genome, a packaging sequence to package RNA into virions; a promoter operably linked to the DNA segment; and a transgene operably linked to a second promoter; b) a BIV packaging vector construct comprising a BIV DNA sequence fragment comprising at least a gag gene or pol gene of BIV; a promoter operably linked to the BIV DNA fragment; and a polyadenylation sequence located downstream of the BIV DNA fragment; and c) an expression vector construct comprising a gene encoding a viral surface protein.

The PCR reactions were performed using two set of primers corresponding to positions 917 and 1628 (primers FIV PCR S 2 and FIV PCR A 2) and 1036-1364 (primers FIV NESTED S and FIV NESTED A) of the P17-P24 region of the FIV gag gene (HOHDATSU et al.
guereza are highly divergent from all known SIV isolates (5), we designed a series of overlapping peptides (16-mers overlapping by 10) across the gag gene, on the basis of the only available Colobus sequence (5).
HIV-specific peptides, as opposed to full-length recombinant proteins, could also potentially be used to resolve antibody cross-reactivity to the products of the GAG gene, which is encountered occasionally in uninfected individuals.
