[Histonet] time in formula 83

[Perry, Margaret]

Our processor has gone down but we can process up to the paraffin step.  My question is how long can we keep the tissues in the formula 83 without any visible problems?  We would like to start processing tonight and possibly infiltrate by hand tomorrow.  Not optimal but it does work.  Your comments are gratefully appreciated.
