Cytek® cFluor® Human Pan Leukocyte Kit, LNW helps researchers to identify and enumerate leukocyte subsets in drug discovery and development, and their other research needs. This has been designed to fully enumerate the complete set of major leukocyte subsets and to mirror and expand on those identified in a traditional complete white blood cell differential. The kit has been optimized to be run on whole blood as a lyse no wash (LNW) assay which, in tandem with a complete blood count (CBC), allows accurate dual platform absolute population counts. Furthermore, the kit has been designed and validated to allow the sequential identification of populations that provides for easy and highly reproducible gating of results. This kit can also serve as a backbone panel which can be expanded upon to further identify any populations of interest, as well as the functional or activation/exhaustion status of a particular population.

The Cytek® cFluor® Human Pan Leukocyte Kit, LNW allows for the identification of more than 20 leukocyte subpopulations, including neutrophils, eosinophils, basophils, lymphocytes, hematopoietic stem cells, monocyte subsets, T cell subsets, B cells, and NK cell subsets in whole blood.

Figure 1. Cell gating strategy for identifying leukocyte subsets using the Cytek cFluor® Human Pan Leukocyte Kit. Data was generated using whole blood collected in an EDTA tube from a healthy donor. Sequential gates of total cells, singlets, CD45+ white blood cells (WBC) are used to get total leukocyte population. CD66b+ WBCs are selected for identifying neutrophils (CD16+) and eosinophils (CD16-). Basophils (CD123+HLA-DR-) are identified in non-CD66b+ population. CD34+CD45dim hematopoietic stem cells (HSC) are identified after excluding granulocytes (Gran) subsets in WBC. Monocytes (Mono) are selected and identified by expression of CD14 and/or CD16 in CD3-, CD19-, CD7-, HLA-DR+ population in non-Gran and non-HSC population. Mono subsets are classified as classical Mono (CD14+CD16dim), intermediate Mono (CD14+CD16+), non-classical Mono (CD14dimCD16+). Total lymphocytes (Lymph) are gated after excluding Gran, HSC, and Mono subsets. CD3+ T cells and CD19+ B cells are identified in Lymph. T cells are further divided into the CD56+ NK-like T cells, and CD4+ and CD8+ T cells from CD56- T cells. From the CD19+ lymphocytes, B cells are sub-populated by CD20 expression. Three subpopulations of NK cells are identified by expression of CD56hi (Early NK), CD56+CD16+ (Mature NK), and CD56-CD16+ (Terminal NK) in CD7+ CD3-CD19- Lymph. 


Whole blood collected in K2EDTA, Heparin, ACD and Cyto-Chex® BCT blood tubes have been tested to validate the performance of this kit. For staining procedures, and gating strategy, please refer to the sample preparation protocols and templates listed below
