Thermo Fisher, 15162, QuantaBlu™ NS/K Fluorogenic Substrate Kit

QuantaBlu™ NS/K Fluorogenic Substrate Kit The Thermo Scientific QuantaBlu NS/K Fluorogenic Substrate Kit is a two-component kit containing proprietary fluorescent substrate and peroxide solutions for non-stopped kinetic assays. QuantaBlu Fluorogenic Peroxidase Substrates allow rapid kinetic ELISA assays to be performed with greater sensitivity than TMB and OPD substratesFeatures of the QuantaBlu NS/K Fluorogenic Substrate Kit:
• More sensitive than TMB, OPD or ABTS substrates
• Large dynamic range (4 log peroxidase concentration range)
• Excellent stability: working solution is stable for 24 hours
• Large stokes shift; excitation/emission maxima of 325/420; range of 315-345/370-460
• Does not photobleachA variety of substrates are available for detecting peroxidase activity in ELISA-based assays. Colorimetric substrates (e.
g., TMB, OPD and ABTS) have been widely used for years. Each of these substrates varies greatly with respect to its performance characteristics such as detection sensitivity, working range and attainable signal-to-noise ratios.
QuantaBlu Fluorogenic Peroxidase Substrate meets all the requirements of an ideal substrate for use in peroxidase detection. QuantaBlu Substrate generates a blue fluorescent product upon reaction with peroxidase. The fluorescent product does not photobleach. Fluorometric-based detection overcomes the limitations of colorimetric substrate detection, which does not allow for quantitation of greater than four optical density units. QuantaBlu Substrate exhibits a flat baseline in assays, which facilitates low-level detection sensitivity and allows for high signal-to-noise ratios.
