Application

Recommended for use in culture medium at a final concentration of 0.4 μg/ml. Incubate cultures for 4-6 hours at 37 °C. Remove medium containing demecolcine, replace with fresh medium.

Biochem/physiol Actions

Often in karyotyping and cell cycle research it is desirable to increase the yield of mitotic cells in a particular phase of the cell cycle. This can be achieved in a variety of ways with the most popular being the use of a cell cycle synchronizing agent such as demecolcine. Demecolcine will arrest cells in metaphase with no remarkable effect on the biochemical events in mitotic cells or in synchronized G1 and S phase cells. White blood cells are often treated with demecolcine to arrest cells in metaphase.

Preparation Note

Reconstitute 1 mg vial demecolcine with 10 mL of sterile balanced salt solution. After reconstitution, store at 2-8 °C or in frozen aliquots at −20 °C. Repeated freezing and thawing is not recommended.

Drugs that target microtubules are thought to inhibit cell division and cell migration by suppressing dynamic instability, a "search and capture" behavior that allows microtubules to probe their environment. Here, we report that subtoxic drug concentrations are sufficient to inhibit

When CHO cells are arrested in S-phase, they undergo repeated rounds of centrosome duplication without cell-cycle progression. While the increase is slow and asynchronous, the number of centrosomes in these cells does rise with time. To investigate mechanisms controlling this
