How are the supernatants resulting from the first two spin steps of the PAXgene Bone Marrow RNA kit purification procedure disposed?

The supernatants resulting from the first two spin steps of the PAXgene Bone Marrow RNA Kit purification procedure may still contain biologically hazardous material. We recommend classifying the tube-processed supernatant of the kit as both a biological and chemical waste. Supernatants can be decontaminated by autoclaving and disposed of as chemical waste.  Disposal should be done in accordance with local, state and federal regulations.

CAUTION: Do not add bleach or acidic solutions directly to the sample preparation waste.
