Anti-CD3 monoclonal antibody (OKT3)
The anti-CD3 monoclonal antibody (OKT3) recognizes CD3, a human glycoprotein and member of the Ig superfamily—primarily expressed on T cells, some NKT cells, and thymocytes during T-cell differentiation. Binding of an anti-CD3 monoclonal antibody to CD3 stimulates T-cell activation. Anti-CD3 antibodies (the OKT3 clone in particular) are used to expand T cells in culture for use in adoptive immunotherapy. CD8+ T-cell expansion can be further enhanced by costimulation with RetroNectin reagent.

T-cell expansion
RetroNectin Recombinant Human Fibronectin Fragment and RetroNectin GMP grade have widespread use as enhancers of retroviral or lentiviral gene transfer into hard-to-transduce cell types. Here, we present data on an additional application—the improved expansion of T cells from PBMCs and increased production of naïve T cells—using a combination of our products: GT-T551 T-cell medium, RetroNectin reagent, CultiLife culture bags, and anti-CD3 antibody.

Scale up transduction of hematopoietic cells with CultiLife culture bags
CultiLife culture bags provide a closed, sterile, gas-permeable system that reduces the risk of culture contamination and user exposure to cell culture materials. A 300-ml format (which can be coated with RetroNectin reagent) is available for high-efficiency viral transduction of hematopoietic cells and a 1,000-ml format can be used to expand cell cultures following transduction. View our protocol and see how to set up your cell culture in a single small bag and then expand it into multiple larger bags.
