Technical Data
Colcemid (Demecolcine, BRN 2822892)
Biochemicals Storage: 4C/-20CShipping: Blue Ice
Anti-cancer compound. Cell synchronization agent. Used as a drug in chemotherapy by synchronizing tumor cells at metaphase, the radiosensitive stage of the cell cycle. Microtubule assembly inhibitor. Depolymerizes microtubules and limits microtubule formation (inactivates spindle fibre formation). Inhibits mitosis during cell division at metaphase by inhibiting spindle formation. Low concentrations affect microtubule dynamics and cell migration, while high concentrations promote microtubule detachment from microtubule organizing center. Apoptosis inducer. Thrombopoietic agent.

Storage and Stability:
Short-term Storage: +4C
Long-term Storage: -20C
Stable for at least 2 years after receipt when stored at -20C.
