PGA and PLLA processing

From:"Bobst, John"

Does anyone know of any adverse reactions or cautions to take when
processing either PGA or PLLA?

I will be processing sheep spine that have either a PGA or PLLA cervical
plate. They are currently being fixed in 70% EtOH, but I wanted to know of
any other cautions I should take before I process and embed them in Spurr
plastic for undecalcified sectioning.  I use increasing alcohols then
acetone before they go into a half and half mix of Spurr and acetone then
finally, full Spurr.

Thanks in advance.
