This can happen on occasion due to transport or storage at lower temperatures. The reagent functionality is not affected; however, the precipitate can be resolved by heating the reagent to >37 °C.

No, tissues do not need to be homogenized.

Transfer tissues in to DNA RNA Shield at room temperature, submerge. Tissue can be homogenized or stored frozen prior to homogenization.

Yes, sort directly into DNA/RNA Shield (e.g. Collect 100 µl of FACS sorted cells into minimally 400 µl of DNA/RNA Shield).

DNA & RNA (<-20°C): Indefinitely

RNA > 1 month
DNA > 2 years

DNA/RNA Shield can be used on a wide variety of sample types including cells, tissues, biological fluids (plasma, serum, saliva, urine), and environmental samples (feces, plants, swabs, etc.).

Yes, extracted nucleic acids are stabilized in DNA/RNA Shield. Prior to downstream applications, clean-up the sample via the appropriate Zymo Research clean-up kit (Genomic DNA Clean and Concentrator (gDCC), DNA Clean and Concentrator (DCC), and RNA Clean and Concentrator (RCC)).

Yes, the product can be customized, including but not limited to: label, fill, number of glass beads, packaging, and more. See more options on the Custom Solutions Page.

Avoid mixing the reagent and bleach (sodium hypochlorite) or other strong oxidizing agents and acids. Clean up any accidental spills with water first.
