LAG-3, Human (HEK293, mFc)

LAG-3 (lymphocyte activating gene 3) protein is an inhibitory receptor on antigen-activated T cells and is critical for immune regulation. LAG-3 binds to FGL1 and transmits inhibitory signals that negatively affect CD8 (+) and CD4 (+) T cell proliferation, activation, and effector functions. LAG-3 Protein, Human (HEK293, mFc) is the recombinant human-derived LAG-3 protein, expressed by HEK293 , with C-mFc labeled tag.
