Leírás

Általános leírás

Tris base, also known as Trometamol or Trizma base, plays a crucial role in diverse research applications as a biological buffer. Widely utilized in buffer formulations like TAE and TBE buffers, its pKa of 8.1 renders it well-suited for maintaining pH within the physiological range (pH 7.0-9.0) applicable to most living organisms. Researchers, however, need to be cautious when studying proteins, as Tris may potentially interfere with the activity of certain enzymes.

This compound can be employed independently as a buffer or as part of mixed buffer formulations, including Tris-EDTA (TE) buffer, Tris-acetate-EDTA (TAE) buffer, Tris-borate-EDTA (TBE) buffer, among others. Notably, Tris base is pure, essentially stable, and relatively non-hygroscopic.

In laboratory settings, Tris base proves indispensable for preparing buffers compatible with biological fluids, serving as a standard pH solution, and facilitating various procedures such as lactate dehydrogenase assays, in situ hybridization, and protein extraction from cells. Its versatility extends to applications in cell culture, biochemistry, and molecular biology labs, where it aids in studies related to cell membrane permeability and buffer preparation.

Alkalmazás

Trizma has been used:

• As a component in the culture of human embryonic stem (hES) cells on human and mouse feeder cells
• As a component of pre-hybridization buffer in in situ hybridization
• To suspend dried protein before SDS-PAGE protein characterization
• As a component of lysis buffer to wash and lyse cells before immunoprecipitation
• In the extraction and enrichment of membrane proteins for separation by two-dimensional polyacrylamide gel electrophoresis
• In studies of double stranded complexes of peptide nucleic acids (PNA) and their complementary DNA sequences, by use of anion exchange HPLC
• In capillary electrochromatography and UV analysis of tocopherols and tocotrienols
• as a component of Tris/base solution in a sulforhodamine B (SRB) assay

Egyéb megjegyzések

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.
