Description

CTX-471 is a fully human monoclonal antibody of CD137. CTX-471 has bind affinity for recombinant human, cynomolgus macaque CD137 and mouse CD137 with Kd values of 50 nM, 61 nM and 748 nM, respectively. CTX-471 can be used for the research of immunomodulation and cancer[1].

IC50 & Target

Kd for CD137: 50 nM (human); 61 nM (cynomolgus macaque); 748 nM (mouse)[1]

In Vitro

CTX-471 (5-500 nM) has bind affinity for recombinant human, cynomolgus macaque CD137 and mouse CD137 with Kd values of 50 nM, 61 nM and 748 nM, respectively[1].
CTX-471 binds to a unique epitope on CD137[1].
CTX-471 (0.1-100 nM; 1, 10 μg/mL; 3 days) increases IFN-y production by human T cells in an Fcy receptor-dependent (FcyR-dependent) manner in vitro[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

CTX-471 (i.p.; 150 μg) exhibits curative monotherapy activity in various syngeneic tumor models and shows a unique ability to cure mice of very large tumors. CTX-471 (i.v.; 10-80 mg/kg; on days 0, 7, 14, and 21) is well tolerated, with no signs of hepatic toxicity in high doses.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
