Introduction
The most reproducible and accurate method of determining the amount of microtubule content versus free-tubulin content in a cell population is to use western blot quantitation of microtubule and free-tubulin cellular fractions.  The general approach is to homogenize cells in microtubule stabilization buffer, followed by centrifugation to separate the microtubules from free-tubulin pool. Then the fractions are separated by PAGE and tubulin is quantitated by western blot. The final result gives the most accurate method of determining the ratio of tubulin incorporated into the cytoskeleton versus the free-tubulin found in the cytosol. This kit contains all the reagents to perform this assay.
