Flash frozen and formalin-fixed paraffin-embedded (FFPE) tissue specimens provide alternatives to fresh samples.
These methods of tissue preservation maintain chemical physiology and structural integrity respectively, permitting long-term storage without degradation. We provide flash frozen and FFPE samples from normal and pathology verified diseased tissue from an extensive range of indications and tissue types.
Flash frozen tissue specimens are unfixed, fresh surgical samples which are frozen at -80°C within 30 minutes of resection. FFPE specimens are sections of fresh tissue which have been fixed in formalin and embedded within a paraffin block.
