The LAG-3 Immune Checkpoint

FGL1 - New Major LAG-3 Ligand
  • Fibrinogen-like Protein 1 (FGL1), a molecule secreted by the liver and pancreas, is a major ligand of LAG-3.
  • FGL1 binding to LAG-3 inhibits T cell response.
  • FGL1 is upregulated in human cancers. High plasma FGL1 levels are associated with poor clinical outcome in patients treated with anti-PD1 therapy.

LAG-3 Pathway

NEW FGL1 Proteins 
Fc (human):FGL1 (mouse) (rec.)
Fc (human):FGL1 (human) (rec.)
FGL1 (human) (rec.) (His)

AdipoGen Life Sciences developed new FGL1 proteins for LAG-3 and Immuno-Oncology Research. Fc (human):FGL1 (mouse) (rec.) (Prod. No. AG-40B-0185), Fc (human):FGL1 (human) (rec.) (Prod. No. AG-40B-0184) and FGL1 (human) (rec.) (His) (Prod. No. AG-40B-0186) are all produced in HEK 293 cells. The Fc-chimeric proteins are both produced as dimeric proteins, while the His-tagged protein is a monomeric construct. Low endotoxin levels and in-house performed binding studies on LAG-3 proteins make these new proteins valuable tools to study LAG-3 and its antitumor activity. Biological activity studies of these FGL1 proteins are ongoing.

Potent LAG-3 Recombinant Protein
LAG-3 (mouse):Fc (mouse) (rec.)

The Fc-chimeric protein LAG-3 (mouse):Fc (mouse) (rec.) (Prod. No. AG-40B-0039) binds to human and mouse MHC class II. This protein induces maturation of mouse dendritic cells in vitro. It induces CD4 and CD8 antigen-specific T cells responses when co-injected in mice, together with the antigen. This protein has been produced in CHO cells as a high purity and low endotoxin research tool.

Standard LAG-3 Blocking Antibody
anti-LAG-3 (human), mAb (blocking) (17B4)

AdipoGen Life Sciences' anti-LAG-3 (human), mAb (blocking) (17B4) (Prod. No. AG-20B-0012) is a monoclonal antibody that recognizes human LAG-3 and works specifically in ICC, IHC (frozen sections), IP, WB and Functional Application. The antibody inhibits LAG-3 and MHC class II interactions. Especially the IHC competence makes this antibody a valuable research tool in human studies.
