I purchased anti-HA polyclonal antiserum from Boehringer Mannheim. It
was not in the catalog but technical services can give you the cat# and
price. This ab used to belong to Babco, who now only offer a monoclonal
which they claim is the same or better than their former polyclonal. I
went with the tried and true.
