Quavonlimab
Based on 1 Customer Validation
Quavonlimab (MK-1308) is a humanized IgG1 monoclonal antibody targeting CTLA-4. As a competitive inhibitor of CTLA-4, Quavonlimab blocks the binding of CTLA-4 to its ligands CD80 and CD86. Quavonlimab increases interferon production, expands and activates T cells, reduces tumor regulatory T cells, inhibits tumor growth, and induces the proliferation of Ki67-positive CD4 and CD8 cells. Quavonlimab can be used in studies related to solid tumors.

生物活性
Human IgG1 kappa
Human
CTLA4
Quavonlimab binds CTLA-4 with low nanomolar affinity, blocks CTLA-4 ligand interactions, and enhances interferon-γ production in human T cell/monocyte-derived dendritic cell mixed lymphocyte reactions, with greater activity when combined with pembrolizumab (HY-P9902)[2].

Flow Cytometry analysis of Raji cells labelling CTLA4 (red) with Quavonlimab (HY-P99809). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then cells were stained with the primary antibody at 1/200 dilution for an hour at 4℃. Goat Anti-Human IgG H&L (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 Isotype Control (HY-P99001, blue) was used as the isotype control.
