Vous avez recherché : Enzymes
Les enzymes accélèrent les réactions chimiques et sont reconnus pour catalyser plus de 5000 types de réactions. La plupart sont des protéines, quelques-unes sont des molécules d’ARN catalytiques.
Choisissez des enzymes pour séparer des liaisons, éliminer de l’ADN génomique à partir de préparations d’ARN, produire des fragments de protéines ou pour une utilisation en chromatographie d’échange d’ions. Les enzymes sont utilisées dans l’industrie chimique et autres applications industrielles lorsque des catalyseurs très spécifiques sont nécessaires.

Acetyl coenzyme A trilithium salt trihydrate, MP Biomedicals
Supplier: MP Biomedicals
Acetyl-CoA is produced via beta-oxidation of fatty acids, via the metabolism of carbohydrates - glucose 6-phosphate to pyruvate to acetyl-CoA and via the catabolism of amino acids. Acetyl-CoA has a number of metabolic opportunities. It is metabolised in the tricarboxylic acid cycle to produce carbon dioxide, water and energy.

Elastase, MP Biomedicals
Supplier: MP Biomedicals
Elastase is prepared from porcine pancreas. It is lyophilised and water soluble. Elastase is chromatographically prepared by the method of Narayanan and Anwar. In the method, 2 times crystalline elastase is adsorbed on a column of DEAE-Sephadex A50 to separate elastase and non-specific protein components. The elastase component is further purified by chromatography on a column of CM-Cellulose using a sodium chloride gradient to elute the elastase. The latter is dialysed until chloride-free and then lyophilised. During its preparation the elastase is held below a pH of 5,5 for greater than 24 hours. Two times crystallised from the euglobin fraction of porcine pancreas by the method of Lewis et al. Does not contain trypsin or chymotrypsin.
