PreservCyt and breast biopsies

From:Laurie Colbert

Does anyone have experience with breast biopsies received in PreservCyt
(for the Thin Prep machine) and subsequent immunos?

We occasionally receive breast core biopsies in the PreservCyt and then
we transfer the biopsies into formalin and process routinely.  Our
pathologist is saying that ER, PR, and Ki67 do not stain well.  I
believe the PreservCyt is basically an alcoholic formalin, but I'm not
positive.  Any comments??
