  • ONPG

    RPI (Research Products International)

    Colorimetric and spectrophotometric substrate for detection of β-D-Galactosidase.

  • Reconstitute with 1.1mL sterile dH2O to achieve a 45mg/mL solution. Store in Freezer.

  • HardyDisk™ ONPG Differentiation Disk is used to differentiate members of the Enterobacteriaceae and other microorganisms based on beta-galactosidase activity. Each cartridge contains 50 disks that are spring loaded for smooth and reliable dispensing from the single metal disk dispenser by…

  • Onpg B Gal Assay Kit

    Oz Biosciences

    The ONPG assay kit is ideal to quantify high expression level of beta-Gal. The levels of active beta-Gal expression can be quickly measured by its catalytic hydrolysis of ONPG (o-nitrophenyl-beta-D-galactopyranoside) substrate to a bright yellow product (Absorbance at 405-420nm).LacZ is one of the…

  • ONPG ELISA Beta-Galactosidase Substrate is a useful detection for ELISA.

  • …specific and can act on simple galactosides including the ONPG (o-nitrophenyl-β-D-galactopyranose) substrate. ONPG hydrolysis results in the release of galactose, and the yellow chromogenic compound, o-nitrophenol. The test substrate, ONPG, does not depend on an induced or constitutive permease…

  • A combination of 12 tests for identification of Salmonella species. (Kit contains sterile media for MR test, Voges Proskauer?s test, Urease production, H2S production, Citrate utilization, Lysine utilization, ONPG tests and 5 different carbohydrates.

  • This product has been assayed against 1.0 µg of biotinylated IgG in a standard capture ELISA using ONPG as a substrate for 30 minutes at room temperature.  A working dilution of 1:100 to 1:3,000 is suggested for this product. 

  • Synonym: o-Nitrophenyl ß-D-galactopyranoside, ONPG CAS Number: 369-07-3 Empirical Formula (Hill Notation): C12H15NO8 Molecular Weight: 301.25 Beilstein Registry Number: 92207 EC Number: 206-716-1 MDL Number: …

  • …chlorophenol red-β-D-galactopyranoside (CPRG), which is up to 10 times more sensitive than the classic o-nitrophenyl-β-D-galactopyranoside (ONPG) β-Galactosidase assays. This increased sensitivity makes it simpler to measure β-galactosidase activity in cells that are difficult to…

  • …streak used in some laboratories for isolation of Haemophilus when the base medium is Trypticase™ Soy Agar with or without sheep blood. Taxo™ ONPG Discs are used for the detection of lactose fermenters, especially those that do not promptly ferment lactose in some routine identification media…

  • o-Nitrophenyl-β-D-galactoside (ONPG) is a colorimetric substrate for b-galactosidase. This product is hydrolyzed to o-nitrophenol by the enzyme. o-Nitrophenol is yellow in alkaline solution and can be quantitated at 410-420 nm 2 . o-Nitrophenyl-β-D-galactoside is a cell culture…

  • ROCHE B-Gal ELISA

    MilliporeSigma

    …in transfection experiments. Traditionally, β-Gal activity is measured using colorimetric assays with o-nitrophenol-β-D-galactopyranoside (ONPG) or chlorophenol red β-D-galactopyranoside (CPRG) as substrates. These assays are not sensitive enough to detect small amounts of the enzyme.…
