Immunophenotyping of NK Cells
T cells, B cells, and NK cells are the major lymphocyte subsets in peripheral blood. Monocytes are critical mediators of early host immune responses. This multicolor flow cytometry panel allows for easy identification of each cell type.

The NK Cell Phenotype Panel is also available as a multicolor flow cytometry kit (Catalog # FMC033) complete with isotype controls and staining buffer.
Flow Cytometry Gating Strategy for NK Cell Phenotype Panel
NK cell phenotypic analysis over a 14-day time course. NK cells were expanded from PBMCs using plate-bound Anti-Human NKp46 Monoclonal Antibody (Catalog # MAB1850) in ExCellerate™ Human NK Cell Expansion Media, Xeno-Free (Catalog # CCM032) plus rhIL-2 (27 ng/mL; Catalog # 202-IL), rhIL-12 (10 ng/mL; Catalog # 219-IL), rhIL-18 (10 ng/mL; Catalog # 9124-IL), rhIL-21 (10 ng/mL; Catalog # 8879-IL) for 13 days. NK cells were assessed on Days 0, 5, 9, and 13 for expression of human NKp30, CD16, NKG2D, NKp46, CD56 and CD3. Cells were gated on singlets (FSC-A by FSC-H) and live cells (using the Live-or-Dye 405/545 dead cell exclusion dye) and quadrants were set using isotype controls (not shown).
Staining Protocol for NK Cell Phenotype Panel
Other Supplies Required
- PBS
- Flow Cytometry Staining Buffer (Catalog # FC001)
- Fc-block (blocking IgG)
- (Optional) Isotype Control Antibodies
- 5 mL Flow cytometry tubes
- Wash human PBMCs (1 x 106 cells per sample) with 2 mL of Staining Buffer (1X) (Catalog # FC001) or other BSA-containing buffer, by spinning at 300 x g for 5 minutes, using 5 mL flow cytometry tubes. Decant/aspirate supernatant.
- Fc-block cells with blocking IgG (1 μg IgG/106 cells) for 10 minutes at room temperature.
- Add 5 μL of each of the fluorochrome conjugated antibodies. Vortex tubes.
- (Optional) To a separate tube, add 5 μL of each of the isotype control antibodies. Vortex tubes.
- Incubate the mixtures for 30-45 minutes at room temperature in the dark.
- At the end of the incubation, wash with 2 mL of Staining Buffer (1X), by spinning at 300 x g for 5 minutes. Decant/aspirate supernatant.
- Resuspend the cells in 0.2-0.5 mL Staining Buffer (1X) and acquire on a Flow Cytometer.
