<DIV><FONT face=Arial size=2>Dear Histonetters:</FONT></DIV>
<DIV><FONT face=Arial size=2> We would like to clarify
some misinformation circulating recently regarding the availability of
Novocastra products. A Histonet posting by Elliot G. Osterhaus a few weeks ago
incorrectly indicated Novocastra products were no longer available through
Vector Laboratories. We attempted to contact this individual privately to
correct this misinformation. To date, he has not responded to us.</FONT></DIV>
<DIV><FONT face=Arial size=2> Vector Laboratories
continues to be the authorized distributor for all Novocastra antibodies and
products in the United States, Canada, and the UK, as we have been for over the
last 10 years.</FONT></DIV>
<DIV><FONT face=Arial size=2> Sincerely, Judy
Decker</FONT></DIV>
