I just did a CK20 on an H&E and Linda is correct, there is no need to decolorize before doing the CK20. The only thing I would suggest is that you are sure that all mounting media is removed after the coverslip comes off your H&E. The longer it's been coverslipped the more mindful of mounting media removal you should be.

You should have no problem doing CK20 over an H&E. Linda A.

Is it even possible to get a CK 20 positive stain after doing so?
