Background: LAG-3

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.

FAQs for Mouse LAG‑3 PE‑conjugated Antibody

Showing  1 - 2 of 2 FAQs Showing All
  • Q: Can this LAG-3 antibody be used in ELISA? 

    A: We have not validated this particular LAG-3 antibody for ELISA in mouse; however, it has been cited as being used as a detection antibody in a publicatoin (PMID 15946792).

  • Q: I'm using your LAG-3 antibody in western blot but the observed band is a different size than the predicted band size, do you know what the bands are?

    A: There are several alternative splice varients of LAG-3 that could explain the different sized proteins stained by the LAG-3 antibody. It is also believed that there are two secreted forms of LAG-3, one that is about 36 kDa and another at 52 kDa.
