[Histonet] whole retinal staining

[David A. Wright]

Dear Abbey & Histonet

I agree with René Buesa: I would try to stain whole retinae by a 'floating section' method i.e. hand processing in a dipping tray or mesh baskets (brush transfer can be done too but is laborious). Then mount them at the end.

Floating allows reagents to penetrate from both sides of the retina - extra valuable because your incubation times are going to be very long with material this thick. (I assume you are not just interested in superficial layers.) A microwave processor would help with penetration, but I have no direct experience.

Hello out there!

I was wondering if any of you have experience in attaching human retinae (~250-300 microns thick) to slides for manual immunohistochemistry. Starfrost does not seem adequate.

Any advice would be greatly appreciated!
Regards,
Abbey
