Dear all,
Might anyone be able to offer their advice on the best method to retrieve antigens on paraffin embedded skin sections? I am immunostaining for epithelial cytokeratins, and I have block-to-block variation in the quality of the staining - some block give consistently good staining while others giving negligible staining. The tissues were prepared by fixation in 4% PFA for 24 - 48 hours followed by dehydration and embedding. I currently use 15 mins Ficin digestion. I suspect that the differences may be accounted for by variability in the length of time samples were fixed in PFA and then 70% ethanol.
