I am Srikant a PhD student in Queensland University of
Technology,Brisbane,Australia.In a part of my study I am trying to estimate
the element concentration (Na,K,Cl) at various layers of eye
(retina,choroid,sclera) by EDX analysis and confocal microscope.
I am a Pharmacist and don't have very good knowledge of histological
I am using cryosectioning of eye layers and for a fragile layer like retina
I need to cryoprotect before sectioning. I am using snap freezing
My doubts are:
1. As I can't use water soluble cryoprotectant as this will leach all
soluble ion. I wonder how people can keep retina soaked in Ames's solution
and gets fluorescence for chloride ions using dyes like MEQ.
2. Can any one please guide me how I will proceed for cryoprotecting
and sectioning the retina/choroid/sclera with out adverse effects on
3. Can I use PEG as a coating material prior to cryosectioning for
elemental analysis before EDX and confocal microscopy?
