Hello histonetters


 I have been preparing humna skin biopsies for PGP9.5 immunohistochemistry. The
Biopsies are fixed in 2% PLP fixative and cryoprotected in 20%
glycerol/sorennsens buffer. After cutting several specimens on a cryostat they
appear to be insufficinetly fixed. Can tissues that has been cyroprotected be
brought back ro Sorennsens buffered and refixed?

 Any suggestions would be appreciated.
