The Cytek^® 24-Color Mouse Immunoprofiling Panel is designed and optimized by Cytek scientists to enable researchers to identify more than 20 mouse immune subpopulations including T, B, NK cells, dendritic cells, monocytes, and granulocyte populations in fresh mouse samples. The Cytek^® 24-Color Mouse Immunoprofiling Panel has been optimized and titrated for analyzing fresh spleen, bone marrow, lymph node and blood samples on the Cytek Northern Lights^™ or Cytek Aurora^™ systems equipped with violet, blue, and red lasers.

The Cytek^® 24-Color Mouse Immunoprofiling Panel allows for the identification and characterization of multiple lineage subsets within mouse tissue suspensions including T, B, NK cells, dendritic cells, monocytes, and granulocyte populations in fresh mouse samples. The kit has been evaluated in fresh mouse splenocyte, bone marrow, lymph node and blood samples.

DATA

Figure 1: Cell gating strategy for identifying subsets. Data were generated using fresh splenocytes from a C57BL/6 mouse, with red blood cells lysed. Sequential gates of red blood cell exclusion, singlets, and viable CD45⁺ cells are used to distinguish total live splenocytes. After excluding debris from the viable CD45⁺ events, NK cells and CD3⁺ NKT-like cells are identified by expression of CD49b vs. NK1.1, and subsequently gated on CD3 vs. B220. Basophils (CD49b⁺CD45^dim) are identified after excluding the 49b⁺NK1.1⁺ cells. Plasmacytoid dendritic cells (PDCs, CD317⁺⁺B220⁺) are determined after excluding the non-basophils. B cells are then identified in the non-PDC cells by positive expression of CD19 when gated vs. B220. From B220^-CD19^- gated events, γδT cells are identified by co-expression of CD3 and TCRγδ. From the non-γδ-T events, T cells are gated on the CD3 vs. TCR beta plot (gating on CD3⁺TCRb⁺). CD4⁺ and CD8⁺ T cell subsets are distinguished from the total T cell gate (CD4⁺CD8^- and CD8⁺CD4^- events) and then further subdivided into naïve and memory subsets by expression of CD62L and CD44 for each T cell subset (CD4⁺ and CD8⁺). CD4⁺CD25⁺ T cells (containing activated and regulatory T cells) can be identified from the CD4 vs. CD25 plot. Dendritic cells (DCs) are gated on a CD11c vs. I-A/I-E plot from the non-T cell events. DCs are further subdivided into cDC1 and cDC2 populations using CD8 vs. XCR1 and CD4 vs. CD11b plots respectively. From non-DC cells, neutrophils and eosinophils are identified using Siglec F (CD170) vs. Ly-6G. The Siglec F (CD170)/Ly-6G double negative events are then used to classify macrophages (MERTK⁺CD64^+/-) from the non-macrophage events. Total monocytes are identified by expression of CD11b⁺ and are subsequently gated to determine Ly-6C⁺ and Ly-6C^- monocyte subsets using CD11c and Ly-6C.

The panel contains the following single vial reagents.
