[Histonet] re: PCNA

[Kim Tournear]

We always used the Ki67 over the PCNA....docs liked it better and it was always consistent.  Fixative subs can also be issues with HIER and/or enzyme digestion...typically you wouldn't need a harsh HIER or digestion, if any at all, to achieve optimal staining....but not always the case...you just have to be careful of the false (+) and false (-) results....
   
  If you think about it, most detection kits and antibodies are worked up with 10% NBF for most companies....it's a whole different ball game with fixative subs and, in my world  requires too much and too little time to work up new abs...so we stayed with formalin....
   
  Just my 2 cents worth....
