The Lenti-X Concentrator is a complete reagent for the concentration of infectious lentiviral 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 used.

RetroNectin reagent is a 63-kD fragment of recombinant human fibronectin fragment (also referred to as rFN-CH-296) that enhances the efficiency of lentiviral- and retroviral-mediated gene transduction. This is particularly important for hematopoietic cells and other hard-to-transfect cell types. When coated on the surface of containers such as culture dishes, petri dishes, flasks or bags, RetroNectin significantly enhances virus-mediated gene transduction into mammalian cells. This enhanced transduction is thought to result from the colocalization of virus particles and target cells on the molecules of RetroNectin. Viral particles bind RetroNectin via interaction with heparin-binding domain II, and target cells bind mainly through the interaction of the cell surface integrin receptor VLA-4 with the fibronectin CS1 site.

The Flash Therapeutics Inducible Reprogramming Lentiviral Vectors are prepackaged lentiviral particles expressing polycistronic Oct4, Sox2, KLF4, and Myc for reprogramming human somatic cells under the induction of doxycycline using Tet technology. These VSV-G pseudotyped viruses are capable of infecting both dividing and non-dividing cells. The high purification level of these lentiviral particles allows transduction of primary cells and immortalized cell lines without inducing any toxicity to the cells, even at high multiplicity of infection (M.O.I.). The expression of these four factors has been shown to reprogram a variety of differentiated cells into induced pluripotent stem (iPS) cells with embryonic stem (ES) cell-like properties.

Monoclonal antibody produced from mouse hybridoma cells against the wild-type bacterial Tet repressor (TetR). It can be used for detecting TetR-containing proteins on Western blots, and for testing or screening cell lines expressing the Tet-On Advanced, Tet-Off Advanced, or Tet-Off transactivators. It is not recommended for cell lines expressing the original Tet-On or Tet-tTS proteins.
