General description

Cluster of differentiation 69 (CD69) is a type II integral membrane protein, encoded by the gene mapped to human chromosome 12p13.31. CD69 is a member of the C-type lectin family of surface receptors. The encoded protein is expressed in all bone marrow-derived cells, with the exception of erythrocytes.

The antibody FN50 recognizes CD69, an lymphocyte early activation marker.


anti-mju-stimulated human B lymphocyts


The reagent is designed for Flow Cytometry analysis of human blood cells using 10 μL reagent / 100 μL of whole blood or 1e6 cells in a suspension. The content of a vial (1 mL) is sufficient for 100 tests.

Physical form

Solution in phosphate buffered saline containing 15 mM sodium azide and 0.2% high-grade protease free BSA as a stabilizing agent.

Biochem/physiol Actions

Cluster of differentiation 69 (CD69) exerts a pro-inflammatory effect by activating leukocytes. In humans, CD69 negatively regulates immune reactivity. Knockout/ deficiency of the gene increases the risk of susceptibility to autoimmune and chronic inflammatory diseases. The encoded protein might act as a prognostic marker for bendamustine response in chronic lymphocytic leukemia (CLL) patients. CD69 facilitates natural killer (NK) cell function. In addition it also helps in activation and differentiation of a wide variety of hematopoietic cells.
