This video demonstrates a protocol for the magnetic labeling-based isolation of a low-concentration population of CD4+Vδ1+γδ T cells from human peripheral blood mononuclear cells (PBMCs). Using a combination of FITC-conjugated anti-Vδ1 antibodies, magnetic anti-FITC microbeads, and anti-CD4 antibody-coated superparamagnetic beads, the CD4+Vδ1+ T-cells can be successfully purified from the PBMC population.
Protocol
All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board. 1. Isolation of Vδ1 T Cells Take <1 x 106 isolated lymphocytes for an initial FACS determining the frequency of Vδ1 CD4 T cells. NOTE: The population size of this T-cell entity may differ greatly b…
