The products included in the iLite® anti-mTNF-alpha ADCC Activity Set can be used together for the quantification ADCC activity of anti-mTNF-alpha antibodies. 

 Antibody-dependent cell-mediated cytotoxicity (ADCC) is a mechanism whereby pathogenic cells are lysed by lymphocytes, most often Natural Killer (NK) cells. The mechanism involves binding of antibodies to surface antigens on the pathogen. Crosslinking of these antibodies to NK cells through the binding of the Fc-portion to Fc receptors on the NK cells leads to activation of the NK cell and formation of an immune synapse with the pathogenic cell. The NK cell releases cytotoxic granules containing granzymes and perforin into the synapse, leading to apoptosis of the targeted cell (1).

Monoclonal anti-TNF-alpha inhibitors are one of the most commons types of antibody drugs on the market. The mechanism by which these drugs act is most often blocking of soluble TNF-alpha or the TNF receptor. Since TNF-alpha is produced through cleavage of a membrane bound form of the protein, there is a risk that anti-TNF-alpha antibodies bind the membrane bound TNF-alpha and trigger effector functions, such as ADCC. By using the iLite ADCC mTNF-alpha Activity Assay, the risk of an anti-TNF-alpha antibody drug inducing ADCC can be quantified.
