Maria,

Some pertinent questions would be:
	How are you collecting the sample?
	What is the processing schedule?

	I have done some studies here with mouse mammary glands and have
collected the gland including the nipple. I have not had any problems with
cutting.

We shaved the belly being careful around the nipple so as not to injure the
tissue. Cut a thin section on either side of the nipple. Process using ETOH
70%-2 hours, 80% -1 hour, 2 95% ETOH - 20 minutes each, 2 100% ETOH 20
minutes each, 3-Propar 30 minutes each, 4 paraffins 30 minutes each. Embedd
as you would skin. In my hands most mouse tissue requires some soaking prior
to cutting. Be sure the temp of your water bath is not to hot or the fat
beneath the skin will just explode. I find the temperature range to be
fairly narrow.

Hope this is helpful.

Hi Histos!

 

I am having problems with cutting FFPE mouse nipple. Paraffin is cutting
well but small tissue just crushing. We can't collect samples.

Please help, any suggestion is appreciated.

 

Thanks,

Naira
