Specifications for CD69 Antibody, anti-human, REAdye_lease™


Clone REAL271 is an antibody fragment derived from the full CD69 antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAdye_lease Complex to bind markers with high avidity.
Clone REAL271 recognizes the human CD69 antigen, also known as activation inducer molecule (AIM). CD69 is involved in the early events of lymphocyte, monocyte, and platelet activation. Cross-linking of CD69 induces cytotoxic activity and costimulates cytokine production of activated NK cells and selected T cell clones. CD69 is transiently expressed on activated leukocytes including T cells, thymocytes, B cells, NK cells, neutrophils, and eosinophils. It is constitutively expressed by a subset of medullary mature thymocytes, platelets, mantle B cells, and certain CD4+ T cells in germinal centers of normal lymph nodes.
For removal of REAdye_lease fluorochromes for optional relabeling with different fluorochrome-conjugated REAdye_lease antibodies use the REAlease Support Kit (130-120-675).
