Biochem/physiol Actions
解聚微管；在四分体时期阻断有丝分裂。 常用于染色体核型分析与细胞周期研究，以增加停留在细胞周期特定阶段的有丝分裂细胞的产量。可采用多种途径达到该目的，其中最常用的便是使用如地美可辛之类的细胞周期同步化试剂。地美可辛能使有丝分裂细胞或 G1 和 S 期的同步化细胞停留在四分体时期，同时也不会对其生化反应造成明显影响。通常用地美可辛处理白细胞以使细胞停留在四分体时期。

Sigma Aldrich - 27645

Biochem/physiol Actions
Depolymerizes microtubules; blocks mitosis at metaphase. 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.
Other Notes
Binds tubulin hence interfering with microtubule-dependent cell function1

Toronto Research Chemicals - D230785

An antimitotic agent that disrupts microtubles by binding to tubulin and preventing its polymerization. Stimulates the intrinsic GTPase activity of tubulin. Induces apoptosis in several normal and tumor cell lines and activates the JNK/SAPK signaling pa
