[Histonet] Salivary gland tissue fetal pig problems


Hello again,
I want to get salivary gland tissue (parotid, submandibular, sublingual) 
for the students. I thought I would try using the glands from the fetal 
pigs (sent from Carolina Bio) we use for student dissection. I post-fixed 
them briefly (~30 minutes) in 10%NBF, followed by 
dehydration/infiltration. After sectioning, the connective tissue is 
mostly degenerated and the gland tissue doesn't look that good either. The 
good archival gland tissue we have is yellowish-colored, maybe it is fixed 
in something different than NBF. Any suggestions? Thanks.
