FGL1, Mouse (sf9, His)

FGL1 Protein, a potent immune suppressive molecule, inhibits antigen-specific T-cell activation as a major ligand for LAG3. It crucially contributes to LAG3-mediated T-cell inhibitory functions, independently of MHC class II. Secreted by hepatocytes, FGL1 also promotes their growth. The homodimeric form of the protein interacts with LAG3, specifically engaging with its Ig-like domains 1 and 2 through the Fibrinogen C-terminal domain. FGL1 Protein, Mouse (sf9, His) is the recombinant mouse-derived FGL1 protein, expressed by Sf9 insect cells , with C-His labeled tag.
