Commercial sources for antibodies to TrpE or polA

[Roland J Saldanha]

I would like to affinity purify a protein fusion to trpE (derived from the pATH
series of vectors).  I would appreciate any information on commercial sources 
of antibody to trpE (anthranilate synthase) from E. coli.

I am also looking for antibodies directed against polA (DNA polymerase I) from 
E. coli.

Thank you.
