The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

The concentration of amylenes is 100 - 300 ppm.
This product has not been tested for DNase and RNase activity. However, it has been tested and found to be suitable for the extraction of nucleic acids based upon the evaluation of extracted DNA by agarose electrophoresis.
A protocol for using phenol:chloroform or phenol:chloroform:isoamyl alcohol to extract proteins from nucleic acids is described in Molecular Cloning: A Laboratory Manual, vol. 3, pp E.3 - E.4 (1989).
