Tobacco acid pyrophosphatase source?

Hi Chris

 this enzyme is sold by Epicentre, and distributed by Interscience (at
least in Canada).

BTW, if  you plan to map transcription start sites (by TAP-RL-PCR), a
good review has been published in Analytical Biochemistry, a couple of
years ago.

 good luck.
