Brain tubulin microheterogeneity in the mouse during development and aging.


Mouse brain tubulin was analyzed on isoelectric focusing gels. High-resolution gels utilizing Bio-Rad ampholytes (pH 4--6) revealed 5--6 bands in the region corresponding to the alpha-subunit of tubulin and 10 or more for the beta-subunit. The same general banding pattern was observed regardless of the method of preparation of the tubulin. Two species… (More)
