Is it necessary to clean a processor normally used for formalin-fixed tissue before using it with PAXgene Tissue fixed tissue?
FAQ ID - 3607

No. Special cleaning is not required. However, be sure to change the alcohol and xylene (or xylene substitute), and keep separate batches of reagents for processing PAXgene Tissue fixed samples. Reagents contaminated with formalin can lead to reduced nucleic acid yields and integrity.
