This kit provides a complete retroviral vector packaging system for use with any retroviral vector. It is designed to produce virus that can infect dividing cells from a broad range of mammalian and nonmammalian cell types. The GP2-293 Packaging Cell Line contains only the MoMuLV gag and pol genes. The viral envelope portion of the packaging function (env gene) is supplied by transiently co-transfecting one of the Retro-X Universal Packaging Vectors (p10A1, pAmpho, pEco, or pVSV-G) with the retroviral vector. The pQCLIN Retroviral Vector (included in the vector set) can be used as a positive control to constitutively express β-galactosidase in transduced mammalian cells.

The Retro-X Concentrator is a complete reagent for the concentration of infectious retroviral vector particles. This reagent provides a scalable alternative to ultracentrifugation for viral particle concentration. Vector supernatants can be concentrated 10–100 fold, depending upon the volumes and envelope used.

The Lenti-X Integration Site Analysis Kit contains all the reagents needed for PCR-based identification of lentiviral vector integration sites in transduced cell clones. The first step is the construction of pools of adaptor-ligated genomic DNA fragments, referred to as "libraries". These libraries can then be used for identifying genomic DNA sequences flanking the 5' end of the integrated provirus using long-distance PCR.
