[Histonet] re: rat spinal cord longitudinal sections

From:Tracey Couse


I agree with you.  I would section longitudinally so as to limit the 
section number and time analyzing, especially if this is preliminary 
work and you are simply screening.  I work with graduates students who 
currently perform similar studies in the sense that they are looking for 
a fluorescent signal in rat/mouse spinal cord and many of them section 

Good luck!
