HA epitope TAG: is 12CA5 the only Ab available?

Hi Dino,
   The saga of the 12CA5 antibody continues.  BABCO (Berkely Antibody Co.,
Berkeley California), either let their license on 12CA5 antibody lapse, or
gave it up.  Boehringer Mannheim now markets the monoclonal (and gouge for
it if you want my opinion).  Now BABCO markets a polyclonal AB directed
against the HA epitope.  Their antibody is not much cheaper.  Our
laboratory has tested both the monoclonal and the polyclonal.  The
polyclonal definitely has higher background in our hands, despite BABCO's
claims to the opposite.
