[Histonet] Help! Curled cryosections

2010-09-15 Thread Teresa Iglesias
Is there any way to relax curled brain sections? They've been in
 cryoprotectant and I tried sitting them in PBS for a while. They're to be
 used in an IHC- can they be rescued?



 Thanks,

Thanks, Montina
The sections are 40um and I had no trouble with all my other brains
(sectioned myself). I had help with these last two and they are all curled.
I think they just got sectioned too fast or something. I'll try the shaker
and see if it helps.
Thanks!

 Teresa,
 I would put the sections through several 5-10 min. washes on a shaker
 table. It is very important to make sure you have all of the cryoprotectant
 rinsed out of the tissue or it will inhibit IHC staining.  How thick are the
 sections?  Were they cut on a cryostat or freezing microtome?  I routinely
 cut rat brain at 40um and don't have any curling issues.  That sometimes
 occurs when the knife has come through the section of brain too rapidly.  A
 slow and steady motion is needed when cutting frozens.

 Good luck!
