Using the Indian Human immunodeficiency virus type 2 (HIV-2) isolate derived lentiviral vector (LV) system reported earlier, we have derived multiple differently configured transfer vectors. Among the features imparted, the novel ones include a blue/white colony screening platform, a shorter vector backbone candidate and availability of default dual tags. Simultaneously, panels with different utilities were also made using this LV. These include neomycin or puromycin or hygromycin selection markers, with options of default promoter, dual multiple cloning site (MCS) availability and drug inducible transgene expression. All the transfer vectors contain the main MCS with the option of single step sub-cloning of a PCR amplified transgene cassette by T/A cloning strategy apart from cohesive and blunt end cloning sites, as described for the original parent vector. Each transfer vector format was tested by appropriate transgene expression function by transduction of target cells. This is the most comprehensive HIV-2 based lentiviral vector system developed so far and it will significantly aid in preferential applications and thus increase its utility as a versatile system for gene transfer technology.
