Hello Histonet,

I am having a problem with background staining on IHC slides.  This is only happening in cell block specimens.  Is this common on cell blocks?  Should I do a pretreatment on these?  What pretreatments do others prefer?  Should I peroxide quench?  Before or after?  What about blockers?  Do I ramble on and ask to many questions?

Thanks for all your help,
