Nerve biopsies should be fixed in a 10% buffered formalin and the nerve should be left intact-- (at least 2 cm in length). DO NOT CUT to allow for tease fiber preparation and paraffin embedding. If ultrastructural analysis is required , 0.5 cm of nerve must be submitted in 3% glutaraldehyde in phosphate buffer. If the specimen arrives within one hour, it can be submitted fresh, on a saline-sealed Telfa pad in an airtight container.
