Retroviral gene transfer is a widely used technique for efficient introduction of genes into the genome of any dividing cell type for stable expression. ABM's Retro-combo mix is suitable for the packaging of pRetro-E1, -E2, -His, and -HA Retro-Easy™  expression vectors for efficient gene transduction. These pRetro vectors contain a friendly multiple cloning site (MCS) and a Neomycin/Puromycin selection marker, making it easy to clone your gene of interest into our vector and select for it post infection.
