Fig. 2. Specificity of the monoclonal DM1A antibody to
1-tubulin and
3-tubulin, the constitutively expressed and evolutionary highly conserved
-tubulin isoforms, and of rabbit anti-
4-tubulin polyclonal antibody that recognizes only
4-tubulin. Notice that DM1A does not recognize
4-tubulin. There is no
4-tubulin in egg cytoplasm of kavar0/- females. (Dilutions were 500-fold for DM1A and 2000-fold for anti-
4-tubulin.)
