Product Summary for Fc gamma RIIIA/CD16a Antibody (DJ130c) [Janelia Fluor® 669]
Immunogen
CD34 antigen
Reactivity Notes
Reacts with: Macaque
Specificity
NB100-64346 recognizes human CD16, a 50-65kD cell surface molecule, which is the low affinity receptor for IgG (FcR III). CD16 exists as a transmembranous form (Fc gammaRIIIA, or CD16A) and a glycosyl phosphatidylinositol (GPI) anchored form (Fc gammaRIIIB, or CD16B). CD16A is expressed by NK cells, some T cells, and macrophages, whereas CD16B is primarily expressed by granulocytes. In addition, CD16B exists as two allelic variants NA1 and NA2. DJ130c recognizes all polymorphonuclear cells irrespective on their NA phenotype. Studies show that the DJ130c antibody recognizes an epitope in the first membrane-distal domain of CD16 and recognizes both CD16A and CD16B.

Background: Fc gamma RIIIA/CD16a
Activating NK cell receptor function has been harnessed for its potential in tumor immunotherapy (5). One immunotherapy strategy is using bi- and tri-specific NK cell engagers (BiKE and TriKE) to target the Fc gamma RIIIA/CD16a receptor with tumor-associated antigens to stimulate a cytotoxic response and mount an attack on tumor cells (5). CD16a is also capable of antibody dependent cellular cytotoxicity (ADCC) through recognition of antibodies bound to target cells (5-6). CD16-induced NK cell activation allows for NK co-receptor expression including stimulatory receptors like CD137 or inhibitory receptors like TIGIT and PD-1, which serve as additional regulatory checkpoints during ADCC (6). Therapeutic antibodies for cancer treatment like rituximab or trastuzumab can be recognized by Fc gamma RIIIA/CD16a to activate NK cell-mediated killing of tumor cells (5-6).
