I am a PhD. student in Perth, Western Australia who is trying
desperately to purify tubulin for use in an assay to measure tubulin
polymerisation. Ultimately I would like to purify protozoal parasite
tubulin but for now I have been using lamb brain and nematode (Ascaris)
intestine as it is easier to obtain large amounts of material.
So far I have tried using the polymerisation/depolymerisation method of
Shelanski et al. (1973) and the homogenisation, centrifugation and
dialysis method of Barrowman et al. (1984), both of which have been
unsuccessful.
Has anyone any suggestions?
Hopefully,
