Bis-Tris
Based on 1 Customer Validation
Bis-Tris is an amine buffer suitable for protein and nucleic acid systems with a pH buffer range of 5.8-7.2. Bis-Tris can also be mixed with HEPES and cacodylic acid buffer to create a pH 8 environment and monitor fluorescence emission intensity at 305 nm. Gels formulated with Bis-Tris also avoid protein degradation in samples prepared at higher pH (pH 8.5).

Actividad biológica
Bis-Tris (10 mM or 4-12% Bis-Tris gel) has excellent buffering capacity and, in synergy with HEPES and cacodylic acid, covers a wide pH range. It can be used for fluorescence spectroscopy analysis, circular dichroism (CD) analysis, GST pull-down binding assay, gel filtration analysis, nuclear magnetic resonance (NMR) analysis, and protein electrophoresis. Abnormal pH fluctuations can affect experimental results[2][3].
Buffers containing Bis-Tris can be used to preserve purified proteins to prevent degradation (4°C)[2].

Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 1 year; -20°C, 6 months. When stored at -80°C, please use it within 1 year. When stored at -20°C, please use it within 6 months.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
