Dear Dirk,

>In an extract of THP-1 cells there are two very abundant proteins, one
>of Mr 43000 and one of Mr 55000. They both have a pI between 4 and 6.
>I believe the p43 could be beta actin and the p55 tubulin.

I did never make a 2D-PAGE of these cells, but your suggestion is very
probable, since actin and tubulin belong to the most abundant proteins in

Greetings from the tubulin labs...
