生物活性

Halichondrin B is found from the sponge Halichondria okadai. Halichondrin B is a noncompetitive inhibitor of Vinca-alkaloid binding to tubulin (IC50 for tubulin polymerization of 1.2-1.4 μM). Halichondrin B shows anti-tumor activity[1].

体外研究
(In Vitro)

Halichondrin B (0.1-10 nM, 16 h) treatment inhibits the growth of L1210 cells[1].

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

Cell Cytotoxicity Assay[1]

Cell Line: L1210 cells
Concentration: 0.1-10 nM
Incubation Time: 16 hours
Result: Inhibited L1210 cell with IC50 value of 0.3 nM.

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.
