Antibodies to actin and microtubulin.

There are lots of commercially available mono- and polyclonal antibodies. 
We purchase most of them from Sigma. Try 

http://www.sigma.sial.com/sigma/sigma1b.htm

for example. More general informations will be provided by:

http://www-chem.ucsd.edu/Faculty/goodman/antibody.html/abpage.html

you'll find there LOTS of Antibodies and distributiong companies.


In the case of filamentous actin, in my opinion an antibody is never as 
good as decoration with rhodamine-phalloidine. The reason is, that rh-ph 
only binds to actin filaments and not to free globular actin. Depending 
on cell type you may have more background with antibodies.

Hope, it helps
