LAG-3, Rat (HEK293, His)

LAG-3 (lymphocyte activation gene 3) protein is an inhibitory receptor on antigen-activated T cells, which transmits inhibitory signals by binding to ligands such as FGL1. LAG-3 is associated with CD3-TCR at the immune synapse, hinders T cell activation, and may cooperate with PDCD1/PD-1 to act as a co-receptor for PD-1. LAG-3 Protein, Rat (HEK293, His) is the recombinant rat-derived LAG-3 protein, expressed by HEK293 , with C-His labeled tag.
