Application Notes
Peptide ELISA: antibody detection limit dilution 1:16000. Western Blot: Preliminary experiments in Human Lymph Node, Spleen and Tonsil lysates gave no specific signal but low background (at antibody concentration up to 1ug/ml). We would appreciate any feedback from people in the field - have any results been reported with other antibodies/lysates?
Theoretical MW
57 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Alternate Names for LAG-3 Antibody

  • CD223 antigen
  • CD223
  • FDC
  • LAG3
  • LAG-3
  • lymphocyte activation gene 3 protein
  • lymphocyte-activation gene 3
  • Protein FDC

Background

Lymphocyte-activation protein 3 (LAG-3), also known as CD223, belongs to the immunoglobulin superfamily and contains 4 extracellular Ig-like domains. LAG-3 binds to HLA class-II antigens and is involved in lymphocyte activation. It is found on the cell surface of activated NK and T-lymphocytes. The sequence data, exon/intron organization, and chromosomal localization all indicate a close relationship of LAG-3 to CD4.

Limitations

FAQs for LAG-3 Antibody (NB100-57857). (Showing 1 - 4 of 4 FAQ).

  1. What is the concentration of your biotin conjugated LAG-3 antibody?
    • We actuall do not determine the concentration of our conjugated antibodies but they are usuall 80-100% the concentration of the base product, so the concentration should be at least 0.8 mg/ml.
  2. Can this LAG-3 antibody be used in ELISA?
    • 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).
  3. 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?
    • 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.
  4. Is this LAG-3 antibody offered in a smaller size that is less expensive?
    • We do not offer a sample size for this particular LAG 3 antibody but we do offer another, AF3329, in a 25 ug sample size.
