Re: [Histonet] GFP
This has been discussed on Histonet, go to Archives and search, look for
Donna Montague, she has great success with paraffin work unless you are
doing frozen sections.
Formalin and 4% paraformaldehyde will work as a fixatives. You need to
know the difference between autofluorescence and GFP, hopefully the GFP
will fluoresce at maximum level to overcome the autofluorescence. So you
need to have a control, naive or normal (contains no GFP) rat duodenum,
fixed at same time as your experimental animal, and look at this tissue so
you know how autoflourescence appears.
Do not use an H&E, GFP is fluorescent and you need to examine without any
staining to see GFP, hopefully not a wild type GFP but eGFP, or enhanced GFP.
