Hi, Teri:

   Thank  you  for  your  points. In my protocol, I treat the slides 5min
   with  proteinase  K,  but  the my chicken embryo is E4. Maybe I should
   shorten  the  time.  Also,  I want to ask how you do the hybridization
   step.  In  our lab, we drop 100ul hybridization solution with probe on
   the slide and then put a coverslip on it. The day after, we remove the
   coverslip by dipping the slides in the ssc solution. I find it is also
   a reason for losing the structure. Do you have other way to do it?

   Best regards

   Qiaolin
