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.

Supplier: G-Biosciences

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.

Supplier: G-Biosciences

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.

Supplier: Thermo Fisher Scientific

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.
