to determine the morphologic correlate of cold-insoluble tubulin , segments of rat optic nerves were exposed to a series of in vitro experimental conditions that affect microtubules ( mts ) , including cold , podophyllotoxin ( pt ) , triflupromazine ( tfp ) , and taxol , and then examined by electron microscopy .
