You are correct--several companies make abs that recognize his-tagged
proteins, but the epitope to which many of these antibodies bind
includes some residues from the flanking sequence in the vector.
Berkeley Antibody Company (BAbCO) has an antibody that recognizes the
polyhistidine epitope regardless of the flanking sequence. It was
generated by immunizing mice with a polyhistidine tagged protein, and
screening with a different unrelated polyhistidine tagged protein
expressed in an unrelated vector. The resultant antibody can be much
more useful than many of the others, because it can be used to detect
polyhistidine-tagged proteins regardless of the expression vector used.
