<DIV><FONT face=Arial size=2>Dear histonetter,</FONT></DIV>
<DIV><FONT face=Arial size=2>my workmate, who does the IHC on ventana nexes, has
a question about using controls.</FONT></DIV>
<DIV><FONT face=Arial size=2>Do you allways use negativ and positiv controls
with each probe (or with each antibody), if you do the IHC also on a automated
stainer?</FONT></DIV>
<DIV><FONT face=Arial size=2>greetings</FONT></DIV>
