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).

Biological Activity
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].
