I do not know why, but to properly process guinea pig tissues you need a much more rigorous program than what would work for mice. It is very easy to over process mouse tissue. Even rat tissue needs more processing. Guinea pig tissue need a program designed for processing larger animals/tissues, such as one would use to process dogs or even swine.
Let me know what programs you have, and I will get back with you with what would work.

Subject: [Histonet] Processing Guinea Pig
Hello Histonet! I'm a long time reader first time poster. Does anyone have
experience processing guinea pig tissues? I have been processing kidney and
heart but it is consistently coming out mushy in the middle. The mouse
tissue comes out fine even when processed on the same run. I had the tissue
grossed in thinner (2.5mm) thinking that perhaps it was too thick but it
didn't seem to help. Also, it has been fixed in 10%NBF for several days.
I was just wondering if anyone else had similar problems with guinea pig?
I appreciate in advance any advice or tips.
Here is the protocol:
70% etOH 1hr
All under pressure and heat only on the paraffin.
