Description
TAPS is a zwitterionic buffer used with a useful pH range of 7.7-9.1 in biochemistry and molecular biology. TAPS is utilized in capillary electrophoresis of such materials as DNA and DNA-dye complexes.
Dyes have been separated by planar chromatography with electroosmotic flow with 1 mM TAPS in the mobile phase. The stability constants of metal ions with TAPS have been investigated by capillary electrophoresis.
Specifications
• pKa = 8.4 at 25°C.
• Heavy metals ≤ 5 ppm
• Water: ≤ 1.0%
Not for human therapeutic use or for medicinal purposes. For research applications only.
