Ieramilimab
Based on 1 Customer Validation
Ieramilimab (LAG525; IMP701) is a humanized IgG4 monoclonal antibody that binds to LAG-3, resulting in inhibition of LAG-3 interaction with MHC-II molecules. Ieramilimab restores T-cell and NK-cell-mediated antileukemic immunity by reducing exhaustion and augmenting cytokine output and cytotoxicity. Ieramilimab increases the infiltration of cytotoxic T lymphocytes and reduces baseline densities of regulatory T cells (Tregs) and ADAM10-expressing tumor cells. Ieramilimab can be used for the study of various malignancies including melanoma, RCC, and advanced solid tumors.

Flow cytometric analysis of 1X106 Jurkat cells with Ieramilimab (HY-P99027, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG4 kappa (HY-P99003, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
