Re: Strange U shaped lump
This sounds simple enough for me.
Of course, fixing fresh tissue in 10% formalin will give you the best slides for histopathological examination. However, in the past we have fixed brain and liver tissue that had been stored at -70oC and the integrity of the tissue after fixation was very good.
Take ice cold 10% formalin (keep it on ice) and put your tissue straight from the freezer into the ice cold 10% formalin. Leave it in the fridge for 24 hours (depending on size of course) and than you an store it at room temperature. Good luck.
I should add, my freezing process was just popped in the fridge and then in the freezer after a couple days. xD We shall see what damage has occured. Fingers crossed.
