Detection of LAG-3 in Mouse Splenocytes by Flow Cytometry. Mouse splenocytes treated with PMA and Calcium Ionomycin for 3 days were stained with Rat Anti-Mouse LAG‑3 PE‑conjugated Monoclonal Antibody (Catalog # FAB33281P, filled histogram) or isotype control antibody (Catalog # IC013P, open histogram).

Preparation and Storage
LAG-3 (Lymphocyte activation gene-3; also known as CD223 in the human) is a member of the immunoglobulin superfamily (IgSF). The mature LAG-3 protein is a 496 amino acid (aa) membrane protein with a 421 aa extracellular region which contains four IgSF domains, a 21 aa transmembrane region and a 54 aa cytoplasmic region. LAG-3 shares < 20% amino acid sequence homology with CD4, but has similar structure and binds to MHC class II with higher affinity. The mouse LAG-3 extracellular region shares 69% aa sequence identity with human LAG-3.
