Human Lymphocyte Activation Gene 3 (LAG3) ELISA Kit

This Assay Genie ELISA Kit quantifies Lymphocyte Activation Gene 3 (LAG3), a co-inhibitory immune checkpoint receptor expressed on activated T lymphocytes and natural killer cells, in human-derived research samples. Supplied as a 96-assay pack with a colorimetric method, the kit supports immune-oncology, autoimmune disease, and transplant immunology workflows.

LAG3 is widely used as a marker of T cell exhaustion and is investigated alongside PD-1 and CTLA-4 in checkpoint blockade studies. The kit accepts tissue homogenates and cell lysates, allowing laboratories to profile LAG3 expression across patient-derived specimens, primary cell cultures, and experimental disease models. Reagents are configured for research use only and are read on standard microplate absorbance instruments, providing an accessible workflow for tracking LAG3 dynamics during immunotherapy, infection, and inflammation research.
