LaboratoryCD3-CD16+CD56+HLA-DR+ (activated Natural Killer) cells/Cells.CD3-CD16+CD56+ in Blood by Flow cytometry (FC)
Definition
The % activated natural killer (NK) cells can be determined by comparing the number of activated NK cells (CD3-CD16+CD56+HLA-DR+) out of 100 NK cells (CD3-CD16+CD56+). The submitter's lab uses HLA DR antibodies (HLA DR+) for late activation of NK cells within a subpopulation of NK cells that lack CD3 expression (CD3-) and express CD16 and CD56 (CD16+, CD56+).
