[Histonet] species control blocks

[Perry, Margaret]

I have a question for the people who do animal diagnostic work.  How
long do you keep paraffin species control blocks for such tests as
chromogranin a, CD3, CD79a, S100a, cytokeratin etc.  Have you noticed a
decline in antigenicity after a period of time?  How long is it before
you notice a decline?
