Votre recherche pour: 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.

Histo/Zyme

Fournisseur: SIGMA ALDRICH MICROSCOPY

Description: Histo/Zyme is a stabilized proteolytic enzyme in buffered solution, used to unmask immunoreactive sites altered by fixation and/or the embedding process. Treatment with a proteolytic enzyme in immunohistochemistry (IHC) is required to digest excess linkages and expose the antigen. The use of Histo/Zyme results in superior staining over traditionally used enzyme pretreatments, such as pepsin and trypsin. Moreover, Histo/Zyme requires only a brief incubation at room temperature. Performing antigen recovery with Histo/Zyme will allow you to dilute the primary antibody 5 to 10 fold further and achieve optimal staining.

Pig Pepsin (from Stomach)

Fournisseur: SIGMA ALDRICH MICROSCOPY

Description: Pepsin is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In immunohistochemistry (IHC), most commonly used fixatives such as formalin mask tissue antigens (cellular, membrane, and nuclear) by their intrinsic crosslinking. This masking results in poor or no staining in IHC. Pepsin digestion of FFPE tissue sections improves accessibility of antibodies to tissue antigens. Ready to use pepsin reagent, antigen retriever has been used for antigen unmasking in immunohistochemistry.

VWR®, Cod Uracil-DNA glycosylase

Fournisseur: VWR Chemicals

Description: Uracil-DNA glycosylase (UNG), cod is a thermolabile recombinant enzyme produced in <i>E. coli</i> (ung-) using a modified ung gene derived from Atlantic cod. It degrades uracil-containing single- and double-stranded DNA, but not RNA or thymidine-containing DNA, by hydrolysing the N-glycosidic bond between deoxyribose sugar and the base in uracil. This generates alkaline-sensitive apyramidinic sites in the DNA that will be cleaved upon a combination of alkaline conditions and high temperature.
