Rnd Systems Malachite Green Assay

Description: The Malachite Green ELISA Kit is a direct competitive enzyme immunoassay for the quantitative analysis of Malachite green in fish and shrimp samples.

Description: The Fluorogenic HDAC Assay Kit is a complete assay system_x000D_designed to measure histone deacetylase (HDAC) class 1 activity for screening_x000D_and profiling applications. The kit comes in a convenient 96-well format, with all the_x000D_reagents necessary for 100 fluorescent HDAC activity measurements. In_x000D_addition, the kit includes purified HDAC2 enzyme and a potent HDAC inhibitor,_x000D_Trichostatin A, for use as a positive and negative control. The Fluorogenic HDAC_x000D_Assay Kit is based on a unique fluorogenic substrate and developer combination._x000D_This assay method eliminates dealing with the radioactivity, extraction, and_x000D_chromatography aspects of traditional assays. Using this kit, only two simple_x000D_steps on a microtiter plate are needed to analyze the HDAC activity level. First,_x000D_the HDAC fluorometric substrate, containing an acetylated lysine side chain, is_x000D_incubated with purified HDAC enzyme. The deacetylation sensitizes the_x000D_substrate so subsequent treatment with the Lysine Developer produces a_x000D_fluorophore that can then be measured using a fluorescence reader at 485 nm_x000D_(excitation)/528 nm (emission)._x000D__x000D_Our other HDAC kit (#50033) contains a substrate that is excited at wavelengths 350-380 nm and fluoresces at wavelengths 440-460 nm. However, the substrate in this kit fluoresces at longer (green) wavelengths: 485 nm(excitation)/528 nm (emission). It is most useful when the sample or inhibitor fluoresces at wavelengths that overlap those of our other HDAC substrate
