Bis-Tris-d14 is the deuterium labeled Bis-Tris (HY-D0856). 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].
