General description
Tris EDTA is a biological buffer in research. It is a combination of Tris base and EDTA, a metal chelator. Tris provides buffering capacity, maintaining a stable pH in biological samples, while EDTA helps prevent metal ion interference by chelating divalent metal ions. Tris EDTA is often used in molecular biology techniques, such as DNA and RNA sample preparation, electrophoresis, and enzymatic reactions. It helps maintain the stability and integrity of nucleic acids by inhibiting the activity of nucleases and metal-dependent enzymes.
Application
TE buffer is useful for general extraction, suspension, washing, and storage buffer and in the preparation of DNA or RNA. Commonly used for DNA sequencing, restriction enzyme digestion; ligation and polymerase chain reaction (PCR) applications.
Features and Benefits
- BioUltra grade - suitable for many molecular biology applications
- DNase, RNase, phosphatase, and protease-free
- High purity and free of trace metals

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
