Sodium hydroxide ≥97%, pellets
Supplier: MP Biomedicals
1g dissolves in 0.9 mL water; 0.3 mL boiling water, 7.2 mL absolute alcohol, 4.2 mL methanol; insoluble in glycerol. The dissolution of sodium hydroxide in water is a highly exothermic reaction. Sodium hydroxide stock solutions should be stored in plastic containers. Glass containers should be avoided in the preparation and storage of sodium hydroxide solutions because it will etch the glass (typically anything over 2 N will etch glass). Keep solutions protected from air as much as possible since contact with air will form sodium carbonate.

Dithiothreitol (DTT, Cleland's reagent) ≥99.5%, white powder for electrophoresis
Supplier: MP Biomedicals
DL-Dithiothreitol is also known as Clelands reagent; Protective agent for sulfhydryl groups (-SH). Quantitatively reduces disulfides (-S-S- to -SH). In this reaction the DTT is oxidized to the cyclic disulfide which ensures the reduction of other disulfides in solution. Disulfide reduction occurs quickly at pH 8.
Dithiothreitol is useful for stabilizing sulfhydryl containing enzymes. Effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N'-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol.
Useful for stabilizing sulfhydryl-containing enzymes.

Tris(hydroxymethyl)aminomethane (TRIS, Trometamol) ≥99.9%, white crystalline powder, Ultrapure
Supplier: MP Biomedicals
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.
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.
