Tris(hydroxymethyl)aminomethanemolecular biology grade

(TRIS)
C4H11NO3 • Mr 121.1 • CAS [77-86-1]

Tris(hydroxymethyl)aminomethane (Tris) of ultrapure buffer quality for sensitive assays in molecular biology with very low UV absorption, DNase, RNase, Protease not detected.
With a pKa of 8.1 Tris base is optimal for preparation of buffers in the physiological pH range of 7.3 to 7.5.
It is used as a component in buffer solutions in numerous applications:
  • Assays in molecular biology and cytology
  • Extraction of proteins or nucleic acids from cells
  • In situ hybridisation procedures
  • Sample and running buffers for SDS-PAGE
  • TAE- and TBE buffers for agarose gel electrophoresis
  • Transfer buffer for Western Blotting
  • Washing buffers for immunoassays
