Hi all,

I am working with a post doc who wants to inject some "fluorescent
retrograde neurotracers" in to pigs and use paraformaldehyde to fix the
specimens. (Forgive me if I have muddled that up.)

He is being very kind in considering my formaldehyde aversions and 
said he would work after I go home.  He is reluctant to use my
substitute Prefer thinking it may effect the fluorescent signal.

Have any of you worked with Prefer or any other
formaldehyde-paraformaldehyde substitute for that use?  (I have never used
paraform. and have no idea how it differs from formaldehyde.)

I am sure he will want some references if possible.

Thanks,

Trisha
