[RASMB] RASMB Digest, Vol 67, Issue 2

Hi Susumu,

The filtration system which can be incorporated onto the Beckman AUCs is a higher specification than a HEPA filter. I can provide more information if needed.

Best regards,

Anthony

We also run AUC of proteins in serum using commercial human and murine serum (ref attached). Commercial human serum is usually tested for infectious material before selling but it might need higher level of bio-safety if you use serum from patients.
As for serum from health volunteer, it depends on the guideline of the organization.

I guess AUC has filter not HEPA but "BioSafe optional dual PALL Pharmaceutical-Grade Sterilizing Filters" which is installed for preparative UC at the vacuum exhaust.

Best,
Susumu
