Description
| Application | 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. |
| Other Notes | Standard buffer for use in the physiologic pH range1; Component of a cell-wash buffer that minimizes nucleic acid loss from Cl. perfringens 10543 A2; In chromatin preparation in the protein-free spreading technique for the electron microscopy of DNA and chromatin3. |
