Ffpe frozen
TīmeklisThe two principal methods for tissue preservation for IHC are rapid freezing and FFPE (formalin fixed, paraffin embedded). In frozen tissue preparations, tissue is rapidly harvested into a nonaqueous medium, and subsequently sectioned at very cold temperatures on a cryostat. TīmeklisRNases are inactivated in FFPE samples, whereas frozen tissue still contains RNases, which become active as they thaw, which may be contributing to lower yield in the FF …
