[Histonet] URGENT! Questions regarding snap freezing in liquid nitrogen with isopentene


Hi everyone,

I am an Honours student, currently finishing up my Honours thesis. 
I am wondering if anyone could give me some REFERENCES on snap freezing mouse 
tissues using liquid nitrogen and ISOPENTENE. I have used liquid nitrogen ONLY 
for snap freezing my mouse tissues in my project, but not with isopentene. And 
i have been having cryostat sectioned mouse tissues that have a lot of tissue 
degeneration, as well as artefacts after fixing in 2% para & 0.5% Glu, and i 
got the idea from someone that this maybe due to the fact that i did not use 
isopentene in the snap freezing process.

So what i want is to discuss this in my thesis. So it would be great if 
someone could give me any scientific references/comments/advice on this method 
whereby isopentene is used in the snap freezing process, and why using this is 

I have been doing some internet searching myself, but any advice or help from 
all histo experts out there would be greatly appreciated.

Best regards,
