生物活性

Lorigerlimab (MGD019) is a bispecific IgG4 dual-affinity re-targeting antibody (DART). Lorigerlimab can block PD-1 and CTLA-4, and improves T-cell responses. Lorigerlimab can be used for research of metastatic castration-resistant prostate cancer (mCRPC)[1][2][3].

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.
