Re: mouse monoclonal on mouse tissue

From:Carrie Kyle-Byrne

i beg to differ gayle.  i've done several mouse-on-mouse (most recent
notable is Ki-67 (clone MM1)) that have no or very little background using
our standard protocol (using Dako Envision+/DAB) with no additional
blocking.  i find it less time consuming if i try the aby first with no
special protocol and only go to the "mouse-on-mouse" stuff if absolutely
