Re: CK 20

From:Tara Miller

We are using DAKO for our CK20 at a 1:50 dilution at 32 min. and a 
pretreatment of protease 1 for 4 min on our Ventana ES. We do our CK20 
ususally in tandom with CK7 - so our control blocks have both colon and lung 
in them. We just started doing both of these stains a few weeks ago and both 
stains are coming out beautifully.
