  • USE OF ARGON AS A TISSUE FIXATION PRESERVATIVE
    Publication number: 20150216161
    Abstract: The invention may be broadly defined as the addition of Argon to FFPE procedures as an RNA stabilizing agent. Argon is an inert gas from the Noble gas group with low saturation concentrations in water. It is therefore highly surprising that Argon would have any effect on RNA stability in the presence of Formalin, or any other chemical. This property of Argon appears to be specific in that other inert gases fail to show any RNA stabilizing effect.
