AW: [Histonet] Re: paraffin processing times for brain
Stephen, we doubled the routine protocol for braintissue from 13 to 24 hour. We stayed at one hour for the formalin steps, because the tissue is fixed for several days before processing. This protocol is also used for prostate big cassettes.

Currently the blocks have cut and stained well but 4-5mm thick tissue has expanded (bulged out) following cutting as if they had absorbed water.

we used to do one hour in each step formalin through to paraffin (2 steps of paraffin). But 4 to 5mm is a little on the thick side. We used to try for 3 mm. But didn't always get it that way.
