Anti-LAG3 (Lymphocyte Activation Gene 3 Protein, LAG-3, Protein FDC, CD223, FDC)

LAG-3 is a member of the immunoglobulin superfamily (IgSF). The mature LAG-3 protein is a 496aa membrane protein with a 421aa extracellular region which contains four IgSF domains, a 21aa transmembrane region and a 54aa cytoplasmic region. LAG-3 shares <20% aa 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. Applications: Suitable for use in Flow Cytometry. Other applications not tested. Recommended Dilutions: Flow Cytometry: 2.5ug labels10e6 cells, Optimal dilutions to be determined by the researcher.
