U heeft gezocht op: Enzyme-assays

Either measuring substrate consumption or overall production, the enzyme assays are used to monitor enzymatic activity. Provided with the required supplies and reagents for any preferred method, enzyme kinetics and inhibition studies can be successfully completed. While continuous assay sampling methods give activity readings throughout development, discontinuous techniques calculate after the reaction has been stopped. The standardized enzyme assays will provide accurate identification and measurement of the protein molecules present in samples.

Protease Estimation Assay Kit, ProteSEEKER™

Catalogus nummer: (786-325)
Leverancier: G-Biosciences
Omschrijving: 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.

Fluorescent protease assay, Fluoro™

Catalogus nummer: (786-320)
Leverancier: G-Biosciences
Omschrijving: The Fluoro™ Protease Assay Kit is designed for the quantitative determination of proteases present in a protein sample. The assay uses fluorescein isothiocyanate (FITC)-labelled casein as a general protease substrate. The fluorescein label on the FITC-casein is highly quenched. When the proteases present in the sample of interest digest the FITC-casein substrate into smaller peptides, the quenching of the fluorescence label is relieved and the fluorescence of the substrate is increased. The fluorescence of the FITC-labeled peptide is measured with excitation at 485 nm and emission at 530 nm to determine protease activity. The kit detects picogram level of proteases present in the sample.

Product Image-OZBIGO10001

ONPG assay kit

Catalogus nummer: (OZBIGO10001)
Leverancier: OZ BIOSCIENCES
Omschrijving: ONPG assay kit is ideal to quantify high expression level of beta-Gal.
UOM: 1 * 1 Kit
Product Image-786-440

Peroxide assay kit, PEROXsay™

Leverancier: G-Biosciences
Omschrijving: PEROXsay™ is a colorimetric quantitative peroxide assay that measures the oxidation of ferrous (Fe²⁺+) ions to ferric (Fe³⁺) ions. Peroxides react with a sugar alcohol converting it to a peroxyl radical that subsequently starts the oxidation of ferrous ions to ferric ions. The acidic pH of the assay allows the ferric (Fe³⁺) ion to complex with the colorimetric reagent, resulting in a change in absorbance that is proportional to the peroxide concentration.

Product Image-786-431

SAM Methyltransferase assay, SAMfluoro™

Catalogus nummer: (786-431)
Leverancier: G-Biosciences
Omschrijving: The SAMfluoro™ assay is a fluorescent, continuous enzyme coupled assay that can continuously monitor SAM-dependent methyltransferases without the use of radioactive labels or endpoint measurements.
UOM: 1 * 1 EA
Product Image-PIER16159

Pierce™ Gaussia Luciferase Flash Assay Kit

Leverancier: Thermo Fisher Scientific
Omschrijving: The Thermo Scientific Pierce Gaussia Luciferase Flash Assay Kit provides researchers with the most sensitive assay for transcriptional activity of regulatory elements in mammalian cell culture media and whole cell lysate.

Product Image-PIER88317

Serine hydrolase probes, ActivX™ FP

Leverancier: Thermo Fisher Scientific
Omschrijving: The ActivX® FP serine hydrolase probes enable selective labeling and enrichment of active serine hydrolases. Fluorophosphonate (FP) probes specifically label serines of enzymatically active serine hydrolases. FP probes are also effective for screening small molecule inhibitors against enzymes derived from cell lysates, subcellular fractions, tissues and recombinant proteins. Depending on the active-site probe tag group and the enzyme class to be profiled, active site-labeled enzymes are detected and quantified by Western blot, fluorescent gel imaging or mass spectrometry.
