Q: Source of protein G and single chain Ab.

[ronlab]

Hi!

I am looking for plasmids that code for protein G (or its Ab binding 
fragments) or single chain Ab. A had an impression that a modified 
protein G was available through ATCC, but my resent search gave no 
results. I would appreciate any information on how and where such 
plasmids can be purchased. Of cause, generous gifts would be appreciated 
as well.
