CTLA-4 Inhibitor

Futermestotug is a humanized immunoglobulin G1-κ monoclonal antibody targeting human cytotoxic T-lymphocyte associated protein 4 (CTLA4). Futermestotug is promising for research of various malignant tumors.

JMW-3B3 is a humanized IgG1λ monoclonal antibody targeting CTLA-4. JMW-3B3 selectively binds the unique C-terminal sequence of sCTLA-4 to block its immunoregulatory and immunosuppressive activity without cross-reacting with full-length CTLA-4 receptor. JMW-3B3 enhances cytokine profiles in PBMC cultures responding to lupus autoantigen-derived peptides. JMW-3B3 enhances IFN-γ production in anti-CD3 stimulated PBMC from melanoma patients at low anti-CD3 doses. JMW-3B3 can be used for the research of systemic lupus erythematosus and malignant melanoma.

REGN4659 is a fully human anti-CTLA-4 monoclonal antibody and IgG1 antibody. REGN4659 binds to the extracellular domain of human and monkey CTLA-4 with high affinity and specificity. REGN4659 blocks CTLA-4 interaction with CD80 and CD86 ligands. REGN4659 significantly suppresses MC38.Ova tumor growth in CTLA-4 knock-in mice.

ADU-1604 is a humanized IgG1 CTLA-4 antibody. ADU-1604 binds to a unique epitope on CTLA-4 and achieves full blockade of both CD80 and CD86 interactions. ADU-1604 enhances human T cell responses. ADU-1604 demonstrates a favorable tolerability profile. ADU-1604 can be used for melanoma research. Recommend Isotype Controls: Human IgG1 kappa, Isotype Control (HY-P99001).

Anti-CTLA-4/CD152 Antibody (BN13) is a kind of mouse IgG2a κ chimeric antibody inhibitor, targeting to human CTLA-4/CD152. Anti-CTLA-4/CD152 Antibody (BN13) can neutralize CTLA-4 (cytotoxic T lymphocyte antigen-4) also known as CD152. Anti-CTLA-4/CD152 Antibody (BN13) can be used for the researches of infection and immunology, such as human immunodeficiency virus (HIV).

CS2009 is a trispecific antibody targeting PD-1, CTLA-4 and VEGFA. CS2009 blocks the interactions of PD-1/PD-L1, CTLA-4/CD80 and VEGFA/VEGFR2, mediates checkpoint inhibition, and suppresses tumor angiogenesis. CS2009 reactivates PD-1/CTLA-4 double-positive tumor-infiltrating T lymphocytes, induces T cell activation, enhances tumor growth inhibition, promotes vascular normalization, improves T lymphocyte infiltration, and converts the immunosuppressive tumor microenvironment into an immunocompetent one. CS2009 can be used for the research of various advanced solid tumors.

KD6001 is a humanized IgG1κ monoclonal antibody, targeting CTLA4. KD6001 significantly disrupts CTLA-4 interactions with CD80 (IC₅₀: 16 ng/mL) and CD86. KD6001 enhances IL-2 and IFNγ expression in PHA-activated human lymphocytes and exhibits potent antitumor effects. KD6001 effectively inhibits tumor growth in MC38, B16, and Hepa1-6 tumor mice model. KD6001 can be used for cancers research, such as advanced melanoma, hepatocellular carcinoma and liver cancer.

Anti-Rat CTLA-4 Antibody (WKH203) reacts with rat CTLA-4. Anti-Rat CTLA-4 Antibody (WKH203) binds to the CTLA-4 protein disrupts the key signaling mechanisms linked to the suppression of T cell activity, triggering T cells readily and enhancing the immune system’s capacity to identify and eliminate cancer. Recommend Isotype Controls: Mouse IgG1 kappa, Isotype Control (HY-P99977).

GIGA-564 is a fully human anti-CTLA4 IgG1 monoclonal antibody with a K_d of 9.8 nM. GIGA-564 binds to a unique epitope of CTLA-4, mediates FcR-dependent signaling pathways, depletes CTLA-4-highly-expressing regulatory T cells within tumors, and inhibits the proliferation of peripheral regulatory T cells. GIGA-564 exhibits anti-tumor activity in mouse models. GIGA-564 can be used for tumor research.

Anti-Mouse CTLA-4 Antibody (UC10-4F10-11) reacts with mouse cytotoxic T lymphocyte antigen-4 (CTLA-4, CD152). Anti-Mouse CTLA-4 Antibody (UC10-4F10-11) promotes T cell co-stimulation by blocking CTLA-4 binding to the B7 co-receptors, allowing for CD28 binding. Recommend Isotype Controls: Polyclonal Armenian hamster IgG, Isotype Control (HY-P990305).
