General description

Tris(hydroxymethyl)aminomethane, commonly known as Trometamol, Tris base, or Trizma® base, serves a pivotal role in diverse research applications as a biological buffer. Its optimal pKa of 8.1 makes it a preferred choice for formulating buffers like Tris-acetate-EDTA (TAE) and Tris-borate-EDTA (TBE), ensuring the maintenance of pH within the physiological range (pH 7 - 9), applicable to a wide spectrum of living organisms. Despite its utility, researchers need to exercise caution in protein studies, as Tris has the potential to interfere with the activity of specific enzymes.

Tris base may find application as basimetric standard, independently as a buffer and as a crucial component in mixed buffer formulations, including Tris-EDTA (TE) buffer, TAE buffer, TBE buffer, among others. Its attributes include purity, essential stability, and a relative non-hygroscopic nature, making it a dependable choice in laboratory settings. In these environments, Tris base is indispensable for preparing buffers compatible with biological fluids and serves as a standard pH solution. It facilitates various laboratory procedures such as lactate dehydrogenase assays, in situ hybridization, and protein extraction from cells. The versatility of Tris base extends to cell biology, biochemistry, and protein research contributing significantly to studies involving cell membrane permeability and buffer preparation.

Application

Trizma® base has been used:
  • as a component of H buffer (cell dissociation buffer)
  • for washing and saturation of wells in double sandwich ELISA immunoenzymatic technique[1]
  • as an assay buffer for reconstitution of extracted and dried protein samples[2]
  • to prepare Tris-HCl buffer that is used to stabilize proteins
  • as a buffer to extract carotenoid from tubers
  • as a component of sample buffer during protein extraction prior to western blotting[3]
  • as a component of sample buffer for sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE)
  • to prepare simulated body fluid (SBF) for calcium phosphate (CaP) resorption assay
  • as a buffer for polydopamine (PDA) deposition on stainless steel (SS) substrate

Features and Benefits

  • Efficient buffering within the pH range of 7 - 9 with a pKa of 8.1 (25 °C)
  • Tested to confirm low levels of heavy metal contamination, ensuring suitability for various applications
  • Can be used in Cell Biology, and Biochemical research

How does the DRYPOUR® packaging system Improve your operational efficiency?
  • This state-of-the-art design packaging system minimizes caking, thus significantly reducing the time needed for material preparation
  • PE drum with our new tamper-evident seal, a polyethylene liner with integrated desiccant bags and a breathable interior Tyvek® liner
  • Desiccant bags are firmly integrated into the polyethylene liner
  • Triple protection delivers two invaluable results:
  1. Dramatically reduced caking
  2. No contamination risk from the desiccant

Other Notes

For additional information on our range of Biochemicals, please complete this form.
The pH values of all buffers are temperature- and concentration-dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution.
For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. 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.

  3. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. 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.
