The series of FLAG plasmids is sold by IBI. We tried their original
system but discovered errors in their protocols which made it
impossible to isolate proteins on the affinity columns. They have since
updated their product and now have a whole series of plasmids which are
supposed to be useful for expressing specific types of proteins either
intra or extra-cellularly. We have not tried them.
