Product Details

Alternative Name:Lymphocyte activation gene-3, FDC protein, CD223
MW:~180kDa (SPS-PAGE, nonreducing), ~80kDa (SPS-PAGE, reducing)
Source:Produced in CHO cells. The sequence coding for the 4 extracellular Ig-like domains of mouse LAG-3 (D1-D4) is fused to the Fc portion of mouse IgG2a (hinge-CH2-CH3).
UniProt ID:Q61790
Formulation:Liquid. In PBS.
Purity:≥95% (SDS-PAGE)
Endotoxin Content:<1EU/µg purified protein (LAL test; Bio Whittaker).
Species reactivity:Human, Mouse
Specificity:Binds to human and mouse MHC class II.
Biological Activity:Induces maturation of mouse dendritic cells in vitro. Induces CD4 and CD8 antigen-specific T cells responses when coinjected s.c. in mice, together with the antigen.
Applications:Flow Cytometry
Reconstitution:Further dilutions should be made with medium containing 5% fetal calf serum or a carrier protein.
Shipping:Blue Ice
Long Term Storage:-20°C
Use/Stability:Stable for at least 6 months after receipt when stored at -20°C.
Scientific Background:The lymphocyte activation gene-3 (LAG-3, CD223), a member of the immunoglobulin superfamily (IgSF) related to CD4, binds to the major histocompatibility complex (MHC) class II molecules but with higher affinity than CD4. Several alternative mRNA splice-variants of human LAG-3 have been described, two of them encoding potential secreted forms: LAG-3V1 (i.e. the D1-D2 domains of the protein, 36 kDa) and LAG-3V3 (D1-D3, 52 kDa). The longer form was detected by ELISA in the serum of healthy individuals as well as of tuberculosis patients with a favorable outcome. LAG-3 expression by T cell clones correlated with IFN-γ production, and hence soluble LAG-3 has been suggested as a serological marker of Th1 responses.
Regulatory Status:RUO - Research Use Only
