InVivoMAb anti-mouse FGL-1



InVivoMAb anti-mouse FGL-1

The 177R4 monoclonal antibody reacts with mouse Fibrinogen-like protein 1 (FGL-1). FGL-1 is a member of the fibrinogen family of proteins. Under normal physiological conditions, FGL-1 is primarily secreted from hepatocytes and contributes to mitogenic and metabolic functions. FGL-1 is produced at high levels in various tumors including lung cancer and melanoma. High FGL-1 expression is associated with resistance to anti-PD-1/PD-L1 therapy and poor prognosis of cancer patients. Recently, FGL-1 has been identified as a major inhibitory ligand for LAG-3, a receptor that negatively regulates the proliferation, activation, and effector function of T cells. In murine cancer models, the 177R4 clone has been shown to block FGL-1 binding to LAG-3 resulting in boosted T cell activity and slowed tumor growth.

This Antibody Is Useful For:

  • in vivo FGL-1 blockade
  • in vitro FGL-1 blockade
  • Flow cytometry
  • Immunohistochemistry (paraffin)


As always Bio X Cell antibodies are specifically formulated for in vivo use and feature:

  • 95% purity
  • Ultra-low endotoxin levels
  • Preservative, stabilizer, and carrier protein-free


Recommended Control and Buffer:


InVivoMAb rat IgG2a isotype control, anti-trinitrophenol

InVivoMAb rat IgG2a isotype control, anti-trinitrophenol

The 2A3 monoclonal antibody reacts with trinitrophenol. Because trinitrophenol is not expressed by mammals this antibody is ideal for use as an isotype-matched control for rat IgG2a antibodies in most in vivo and in vitro applications.
