Scientific Background
Lymphocyte activation gene 3 protein (CD223/LAG3) is a ~57 kDa protein. Inhibitory receptor on antigen activated T-cells. Delivers inhibitory signals upon binding to ligands, such as MHC class II, its main ligand present at the surface of antigen-presenting cells (APCs), and FGL1, which is secreted by hepatocytes and certain types of tumor cells. Ligand-binding initiates a signaling that inhibits the T-cell receptor (TCR) in the immunological synapse, preventing T-cell activation.
Reactivity
This antibody shows reactivity with Human.
