activation of microtubule assembly is enhanced when extracts are prepared from pc12+ cells exposed for 1 day to 1.0 microm taxol and is abolished when pc12+ extracts are : ( a ) prepared from cells incubated for 1 day with 1 microm colchicine , ( b ) treated with the non-ionic detergent nonidet p-40 or ( c ) centrifuged at 100 000 g instead of 80 000 g .
