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).

Descripciòn

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)[1][2][3].

In Vitro

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].

In Vivo:

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
