We are currently storing AF samples at -80 °C without any additive.

Chaitanya Tellapragada

Thank you so much Dr. Fattuoni. Do you spin down the AF specimen and preserve the supernatant or directly the specimen?

We store the whole specimen. When you will analyse them, after thawing you may vortex them to omogenize and then take the aliquot you need for your analysis

Thank you so much for your advice Dr.Fattuoni.
