Larotaxel (XRP9881) is a taxane analogue with preclinical activity against taxane-resistant breast cancer. Larotaxel (XRP9881) exerts its cytotoxic effect by promoting tubulin assembly and stabilizing microtubules, ultimately leading to cell death by apoptosis. It presents the ability to cross the blood brain barrier and has a much lower affinity for P-glycoprotein 1 than Docetaxel.

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.
