Fournisseur: G-Biosciences

Description: A highly sensitive colorimetric protein assay that overcomes interference of common laboratory agents present in protein solutions and shows minimal protein-to-protein variation. The assay is unaffected by the presence of common laboratory agents such as reducing agents, chelating agents, detergents, amines, sugars, chaotropes, salts, drugs, antibiotics, cobalt, and others.

Description: These assays are non-radioactive methods for detecting specific transcription factor DNA binding activity in nuclear extracts and whole cell lysates. A specific dsDNA sequence containing the NF[kappa]B response element is immobilized on the bottom of the wells in a 96-well plate. The transcription factor is detected by the addition of a specific primary antibody. A colorimetric readout at 450 nm is obtained through a horseradish peroxidase-conjugated secondary antibody.

Description: ProteSEEKER™ identifies specific types of proteases with a panel of twelve protease inhibitors and a sensitive colorimetric protease screening assay. ProteSEEKER™ allows researchers to screen their protein samples and establish which specific class of proteases are present and therefore design a highly specific protease inhibitor cocktail using the minimal number of protease inhibitors. Alternatively, ProteSEEKER™ can be used to test existing protease inhibitor cocktails and identify their inadequacies and therefore supplement in additional protease inhibitors.

Fournisseur: Rockland Immunochemicals

Description: BCIP/TNBT Membrane Alkaline Phosphatase Substrate is an artificially manufactured chromogenic substrate for use in sensitive colorimetric assays. BCIP/TNBT can be utilized in ELISA, in situ hybridization, and IHC. Alkaline phosphatase hydrolyzes the BCIP to 5-bromo-4-chloro-3-indole, which is oxidized by oxygen in the atmosphere, yielding a blue dye. In the presence of TNBT, an insoluble dark blue precipitate is formed after a reduction reaction instead.

Description: Le dosage de protéines Bradford est le dosage colorimétrique privilégié pour quantifier la concentration totale en protéines. Basée sur la formation complexe entre les résidus d'acides aminés basiques et aromatiques avec le colorant Coomassie® bleu brillant G-250, la méthode de Bradford est plus facile, plus rapide et plus sensible que la méthode de Lowry.

Description: Nitrotetrazolium blue (NBT), in combination with BCIP (5-bromo-4-chloro-3-indolyl-phosphate), is required for the detection of labeled probes in western blots. It is part of the colorimetric detection assay. NBT and BCIP dyes detect alkaline phosphatase activity, thereby generating an insoluble purple dye (diformazan). The dye is visible at areas where the labeled probe has hybridised to its target.

Description: 2,2-Diphenyl-1-picrylhydrazyl is used as a sensitive colorimetric free radical scavenger. It serves as a general antioxidant detector. It is utilized to monitor chemical reactions involving radicals as well as a standard of the position and intensity of electron paramagnetic resonance signals. Further, it is employed in the quantitative determination of aliphatic and aromatic thiols by indirect spectroscopy and for photometric determination of tocopherol.

Description: Ce test simple et rapide permet le contrôle de l'hygiène des surfaces de travail. Champs d'applications: industrie agroalimentaire, restauration, produits laitiers, autorité de santé, consultants HACCP. L'échelle colorimétrique pour l'interprétation des résultats est imprimée sur chaque tube. La comparaison de la couleur de la solution avec l'échelle colorimétrique confirme ou infirme la propreté d'une surface. Il suffit de frotter l'écouvillon humide sur une surface avant de l'insérer dans le tube puis de briser le flacon de verre contenu dans le tube à l'aide d'une pince. À la fin du test, le tube peut être évacué avec les déchets courants à température ambiante.
