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

Special cleaning is not required when using a processor that has been used for formalin-fixed samples. However, be sure to change the alcohol and xylene (or xylene substitute), and keep separate batches of reagents (alcohol, xylene, or xylene substitute) for processing PAXgene Tissue fixed and formalin fixed samples (See FAQ 3032 and 3033 ).
