Abstract
Transduction of primary T cells has become prominent with the introduction of chimeric antigen receptor T-cell therapy. Although there are many protocols for the transduction of human T cells, it remains a challenge to transduce murine T cells. We present an optimized protocol for the retroviral transduction of murine CD4 T cells, which overcomes major challenges including large-scale production and long-term culturing of transduced cells. The optimized protocol combines high transduction efficiency with a low rate of cell death. For complete details on the use and execution of this protocol, please refer to Eremenko et al., 2019.
