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. |
Application: | Trizma® hydrochloride solution can be used: • As an elution buffer after PCR cleanup • As an elution buffer after DNA extraction |
General description: | 10 mM Trizma® hydrochloride (pH 8.5) is a widely used buffer in molecular biology applications such as nucleic acid extraction and purification. No mixing or pH adjustment is necessary. Guaranteed accuracy for this buffer is ± 0.2 pH units at 25°C. |
Legal Information: | Trizma is a registered trademark of Sigma-Aldrich Co. LLC |
Other Notes: | Prepared with BioUltra Trizma Base for molecular biology in 18 megaohm UV irradiated water. pH-adjusted and 0.2 μm filtered. The buffer was tested by 35 cycles of PCR for prokaryotic and eukaryotic DNA contamination. To keep the buffer contamination-free, it is recommended to use gloves and barrier-tip pipettes for dispensing. Between uses, keep the bottle closed and refrigerated, away from areas where DNA samples and PCR products may be stored. |
Preparation Note: | Allow the buffer to reach room temperature before use. |
Storage Temp. | 2-8°C |
