生物活性

Robatumumab (Sch 717454) is an anti-human IGF-1R (insulin-like growth factor receptor-1) antibody. Robatumumab shows anti-tumor activity and anti-proliferative activity to cancer cells. Robatumumab can be used in osteosarcoma and Ewing sarcoma research[1][2].

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.
