  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

LAG3 antibody was raised against murine CD223 Ig fusion protein.
Recognizes murine lymphocyte activation gene-3 (LAG-3), a 70kD activation-induced cell surface molecule that is also referred to as CD223. Murine CD223 is expressed on activated CD4 positive and CD8 positive alpha/beta T lymphocytes and a subset of natural killer (NK) cells. CD223 binds to MHC class II molecules with high affinity and is reported to negatively regulate T cell homeostasis and T cell expansion. Recognizes an epitope within the D2 domain of CD223. The antibody is reported to block the in vitro function of murine LAG-3 but studies suggest that the antibody does not block binding of LAG-3 to MHC class II. XXX recommend the use of MCA2386EL for this purpose.
The applications listed have been tested for the base form of this product. Alternate forms, such as conjugated, azide-free, or ready-to-use, have not been tested. Flow Cytometry: Use 10 ul of the suggested working dilution to label 10^6 cells in 100 ul. The Fc region of monoclonal antibodies may bind non-specifically to cells expressing low affinity Fc receptors.


Lyophilized, PBS, pH 7.4, 0.09% sodium azide, 1% BSA.
100 tst Distilled Water.

LAG3 Antibody, CD223 antigen Antibody, LAG-3 Antibody, Protein FDC Antibody, CD223 Antibody, FDC Antibody, Lymphocyte-activation gene 3 Antibody

Lymphocyte-Activation Protein 3 (LAG3) belongs to Ig superfamily and contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. The sequence data, exon/intron organization, and chromosomal localization all indicate a close relationship of LAG3 to CD4.
