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

Assay (titr.) Heavy metals (Pb) Iron Arsenic (As) Magnesium (Mg)
