生物活性

JNJ-70218902 is a bispecific antibody that binds to human TMEFF2 on cancer cells and to human CD3 on T cells. JNJ-70218902 induces an exposure-dependent proinflammatory response and targeted tumor cell lysis, and promotes T cell-mediated tumor cell killing (EC50: 1.4 nM). JNJ-70218902 has a promising potential for prostate cancer research. The recommended isotype control is human IgG4 kappa, isotype control (HY-P99003)[1].

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.
