Biological Activity

Description	Colchicine is a microtubule polymerization inhibitor with an IC50 of 3 nM.
In vitro	Colchicine is a tubulin inhibitor and a microtubule disrupting agent, which inhibits the tubulin polymerization on the site of β-tubulin.^[1]
In vivo	Colchicine prevents NSAID-induced small intestinal injury by inhibiting activation of the NLR family pyrin domain-containing 3 (NLRP3) inflammasome.^[2]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines HeLa cells Concentrations 5 μM Incubation Time 2 h Method HeLa cells are cultured in 6-well plates and then treated with or without different concentrations of KXO1, vinblastine, or colchicine for 2 h before being treated with 100 μM EBI for another 2 h. Total protein is extracted with radioimmuno_x0002_precipitation assay buffer and subjected to Western blot analy_x0002_sis of β-tubulin. GAPDH is used as a loading control. The Western blotting procedure is performed.
