Cytek cFluor™ TBMNK Kit allow for the identification of lymphocytes, total T cells, helper T cells, cytotoxic T cells, NK T cells, B cells, NK cells, total monocytes, nonclassical and classical monocytes in human peripheral blood mononuclear cells and in whole blood.

CD3 is expressed on all mature T cells, NK T cells, and some thymocytes. CD3, a part of the CD3/T cell receptor complex, plays a role in antigen recognition, signal transduction, and T cell activation.

CD4, is expressed on most thymocytes, a major subset of T cells, and on monocytes/macrophages. Functionally, CD4 is associated with thymic differentiation, in conjunction with MHC class II molecules in antigen recognition and with signal transduction.

CD8 is found on thymocytes, on a subset of T cells and on NK cells. This molecule acts as a co-receptor in MHC class I molecules in antigen recognition, has a role in T cell activation and in thymic differentiation.

CD14 is also known as a high affinity LPS receptor and is highly expressed on monocytes and macrophages. It is also expressed on granulocytes, but at a lower level. In addition, CD14 is found on interfollicular dendritic cells, reticular dendritic cells, and Langerhans cells.

CD16 is expressed on NK cells, monocytes and macrophages in the form of CD16a. Another form of CD16, CD16b is expressed on neutrophils. CD16 engagement of IgG leads to NK cell activation, antibody-dependent cell-mediated cytotoxicity (ADCC) and phagocytosis  

CD19 is expressed in the B cell lineage, from pro-B to blastoid B cells. However, it is absent on plasma cells. It is also expressed on follicular dendritic cells. CD19 is involved in B cell development, activation, and differentiation.

CD45 is expressed on all hematopoietic cells, except erythrocytes and platelets. CD45 is a signaling molecule that is involved in cellular proliferation, differentiation and in regulation of immune cell functions.

CD56, within the hematopoietic system is expressed on NK cells and NKT cells, a subset of T cells. In the nervous system, CD56 is expressed by neurons and plays a role in the homotypic adhesion of neural cells.
