A recent Biotechniques article describes a primer pair, and a method
where one can clone the Taq pol gene from T. aquaticus DNA by PCR,
express it in E.coli, and purify it in one step by simply boiling the
cell lysate, as the polymerase is then apprenlty the only enzyme in the
cell which does not denature, aggregate and precipitate. Haven't
tried it myself.
A literature search should point the way. :)
