Multicolor cocktails TBNK

CD3 identifies mature T cells, excluding B and NK cells. It is key in T receptor signalling. CD4 is expressed on T-helper T cells and some monocytes. It is involved in immune activation. CD8 marks cytotoxic T cells and some NK cells. Assists in adhesion and activation. CD16 is found on NK, neutrophils and monocytes. Together with CD56, it identifies NK cells. CD56 is on NK and some T lymphocytes (CD3⁺CD56⁺). It is essential for detecting NK populations. CD45 marks all leukocytes, useful for differentiating them from non-hematopoietic cells. CD19 identifies B cells, does not react with T, monocytes or granulocytes.
