The Bioaim Human LAG3 ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of LAG3 in Human serum, plasma and cell culture media. An antibody specific for Human LAG3 was coated on a 96-well plate. Standards and samples are added to the wells and any LAG3 present binds to the immobilized antibody. The wells are washed and biotinylated anti-Human LAG3 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of LAG3 present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Cell Adhesion;

lymphocyte activating 3 (LAG3) Background: LAG3’s main ligand is MHC class II, to which it binds with higher affinity than CD4.The protein negatively regulates cellular proliferation, activation, and homeostasis of T cells, in a similar fashion to CTLA-4 and PD-1 and has been reported to play a role in Treg suppressive function. LAG3 also helps maintain CD8+ T cells in a tolerogenic state and, working with PD-1, helps maintain CD8 exhaustion during chronic viral infection. LAG-3 limits the expansion of activated T cells and pDC in response to select stimuli. Proteolytic shedding of LAG-3 enables normal T cell activation by removing the negative regulation. Binding of a homodimerized soluble LAG-3/Ig fusion protein to MHC class II molecules induces maturation of immature DC as well as secretion of pro-inflammatory cytokines by cytotoxic CD8+ T cells and NK cells. LAGs is known to be involved in the maturation and activation of dendritic cells.
