Relatlimab  (Synonyms: BMS-986016)

Relatlimab (BMS-986016) is a human monoclonal antibody anti-LAG-3 antibody generated by immunization of transgenic mice bearing human immunoglobulin miniloci with recombinant LAG-3 protein. Relatlimab blocks LAG-3/MHC II interaction with an IC₅₀ value of 0.67 nM and LAG-3/FGL1 interaction with an IC₅₀ value of 0.019 nM. Relatlimab can be used in research of cancer^[1].

Relatlimab (BMS-986016; 0.001-100 nM) recognizes native LAG-3 and binds to primary activated human and cynomolgus CD4+ T cells with EC₅₀ values of 0.11 nM and 29.11 nM, respectively^[1].
Relatlimab (0.001-10000 nM; T cells (3A9-hLAG-3)) enhances peptide responsiveness of T-cell hybridoma 3A9-hLAG-3 and reversals LAG-3-mediated inhibition of T-cell hybridoma 3A9-hLAG-3 with an IC₅₀ value of 1.05 nM^[1].
Relatlimab (0.001-10000 nM; primary T cells) enhances activation of superantigen-stimulated human PBMC cultures and enhances IL-2 secretion^[1].
