Descripción

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.

Application

Trizma^® hydrochloride solution can be used:

• As an elution buffer after PCR cleanup
• As an elution buffer after DNA extraction

Preparation Note

Allow the buffer to reach room temperature before use.

Other Notes

Los valores de pH de todas las disoluciones tampón son dependientes de la temperatura y la concentración. En el caso de los tampones Tris, el pH aumenta alrededor de 0,03 unidades por cada °C de disminución de la temperatura, y disminuye 0,03-0,05 unidades al ser diluido por 10. Para aplicaciones precisas, debe utilizarse un peachímetro cuidadosamente calibrado con un electrodo de vidrio/calomelano combinados.

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.
