The protein I'm studying does not have any homology to tubulin.

I performed an experiment exploiting the fact that my recombinant
protein is 6his-tagged using Reacti-Gel from Pierce. However, I was
not able to get enough antibodies. I guess I can try this experiment
one more time using tubulin-blocked serum solutions.

I'm not sure if I can get them to do it all over again. It takes too
much time and I am trying to beat a deadline.

Thank you so much for your helpful comments and suggestions.
