Paclitaxel CAS NO 33069-62-4 is currently the only known drug that can promote microtubule polymerization and stabilize polymerized microtubules. Paclitaxel CAS NO 33069-62-4 can only form on polymerized microtubules and does not react with non-polymerized microtubule protein dipolymers. After coming in contact with Paclitaxel CAS NO 33069-62-4, cells will accumulate a large number of microtubules within themselves, which disrupts cell functions, especially cell division, which is forced to cease at the mitotic stage.
