TRIS, MP Biomedicals™

Description

TRIS Ultra Pure, ≥99.9%, White crystalline powder

• Tris is used in pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications.
• Tris is used in assays used to characterize the activity and kinetics of the enzymes that catalyze SUMOylation of Small ubiquitin-like proteins (SUMO) and SUMO-dependent protein-protein interactions.
• Tris have been useful as buffers in a wide variety of biological systems.
• It has been used as a starting material for polymers, oxazolones (with carboxylic acids) and oxazolidines (with aldehydes).
• It does not precipitate calcium salts and is of value in maintaining solubility of manganese salts.
• It can be used for the direct standardization of a strong acid solution; the equivalence point can be determined either potentiometrically or by use of a suitable indicator such as 3-(4-Dimethylamino-1-naphthylazo)-4-methoxybenzenesulfonic acid.
• It is RNAse and DNAse-free.Tris is relatively non-hygroscopic;but, if needed, it can be dried at 100°C for up to 4 hours to remove any water.
