Presented is a protocol for the expansion of Gamma-Delta (γδ) T cell drug product. Lymphocytes are isolated by elutriation and γδ-enriched with zoledronic acid and interleukin-2. Alpha-beta T cells are depleted using a clinical-grade magnetic separation device. The γδ cells are co-cultured with K562-derived, artificial antigen-presenting cells and expanded.
