Reconstitute the lyophilized protein in sterile deionized water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.

Upon receiving, this product remains stable for up to 6 months at lower than -70°C. Upon reconstitution, the product should be stable for up to 1 week at 4°C or up to 3 months at -20°C. For long term storage it is recommended that a carrier protein (example 0.1% BSA) be added. Avoid repeated freeze-thaw cycles.

FGL1 (Fibrinogen-like protein 1), also known as hepatocyte-derived fibrinogen-related protein 1 (HFREP-1), HP-041, hepassocin (HPS), and liver fibrinogen-related protein 1 (LFIRE-1), is a liver-specific secreted protein belonging to the fibrinogen superfamily whose members share a fibrinogen domain at their C-termini. FGL1 is an immune suppressive molecule that inhibits the activation of antigen-specific T cells by acting as a major ligand of LAG3, and binds LAG3 independently of MHC class II.
