source of lacI repressor wanted

Is there a commercial (or other) source of purified lacI repressor

Even better for us would be a source of the lacI-NLS fusion protein
from the Stratagene LacSwitch system (i.e. as in their plasmid p3'SS).

Failing those, are there any quick (affinity column based?) protocols
for purifying lacI repressor or derivatives in E. coli?

Any information gratefully received.

Best wishes,
