Beschreibung: DL-Ethionine is a racemic mixture of the anti-methylation agent L-ethionine and its enantiomer D-ethionine. DL-Ethionine is used as a dietary supplement to accelerate cholangiocarcinogenesis in vivo. DL-Ethionine is used to induce oxidative stress in liver to study the levels and activities of anti-oxidative enzymes and compounds such as glutathione.

Beschreibung: Ammonium acetate is a chemical compound which is derived from the reaction of ammonia and acetic acid. Ammonium acetate is volatile at low pressures. Because of which it has been used to replace cell buffers with non-volatile salts, in preparing samples for mass spectrometry. It is used as a buffer for mobile phases for HPLC with ELSD detection.

Beschreibung: Storage: Room Temperature, desiccate, store under nitrogen.
Dimethyl Sulfoxide is a dipola, aprotic solvent. It has been shown to accelerate strand renaturation (1-10% concentration) and is believed to give the nucleic acid thermal stability against depurination.
Dimethyl Sulfoxide is used to enhance dermal absorption of many chemicals, as a solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers, in antifreeze or hydraulic fluids, as a cryopreservative for cell cultures, oxidation of thiols and disulfides to sulfonic acids, as a PCR cosolvent to help improve yields, especially in long PCR. DMSO is routinely used in polymerase chan reaction (PCR), amplification of cDNA libraries, DNA sequencing, column-loading buffers for poly (A)+ RNA selection, buffers for the transformation of competent E. coli, and transfection protocols.
To prepare sterile solutions use a teflon or nylon membrane to sterile-filter the DMSO - do not use a cellulose acetate membrane.

Beschreibung: Dithioerythritol is an erythro isomer of 2,3-dihydroxy-1,4-dithiolbutane, and an isomer of 1,4-dithiothreitol which is a reagent for maintaining thiols in the reduced state; prevents oxidation of sulfhydryl-containing proteins during SDS-polyacrylamide gel electrophoresis. It also quantitatively reduces disulfides.

Beschreibung: Activators: Papain is activated by cysteine, sulphide, sulphite and more. It is enhanced when heavy metal binding agents such as EDTA are also present. N-bromosuccinimide enhances the activity. Inhibitors: Substances which react with sulphydryl groups including heavy metals, carbonyl reagents. Aldehydes are papain inhibitors. Benzoylamidoacetonitrile is an inhibitor. See Shapira and Arnon (1967a and b) on antibody inhibitors. Papain may be inactivated by H₂O₂ generated by γ-irradiation of H₂O⁻ the active SH group being oxidised to sulphenic acid. Specific inhibitors are AEBSF, antipain, cystatin, E-64, leupeptin, PMSF, TLCK and TPCK.
