Wholemoutn beta-gal staining on mouse embryos
I am doing wholemount beta gal stainings on mouse embryos (on a
LacZ-knock-in mice). The well-known problem is the penetrance of the
stain from 10.5 dpc onwards. I have been wondering if someone tried to
skin embryos (maybe a quick scalding would not kill b-gal?) or devised
some other trick to get the penetrance better.
Staining on the frozen sections works but paraffin sections are again a
problem since PF and paraffin embedding seem to kill b-gal.
Any pointers would be greatly appreciated since my googling around did
not produce any decent result.
