Enzo Life Sciences ROS-ID Superoxide detection kit (1Kit)

Enzo Life Sciences’ ROS-ID Superoxide detection kit is designed to directly monitor real time superoxide production in live cells using fluorescence microscopy and/or flow cytometry. A major component of the kit, Superoxide Detection Reagent (Orange), is a cell-permeable probe that reacts specifically with superoxide, generating an orange fluorescent product. The kit is not designed to detect reactive peroxide, hydroxyl, peroxynitrite, chlorine or bromine species, as the fluorescent probe included is relatively insensitive to these analytes. Upon staining, the fluorescent product generated can be visualized using a wide-field fluorescence microscope equipped with a standard orange (e.g., 550/620 nm) fluorescent cube, or cytometrically using any flow cytometer equipped with a blue (488 nm) laser. Applications: Flow Cytometry, Fluorescence microscopy, Fluorescent detection, HTS .

AdipoGen Rhodamine 110 chloride,Chemical. CAS: 13558-31-1.

Rhodamine 110 chloride, AdipoGen Life Sciences. Chemical. CAS: 13558-31-1. Formula: C20H14N2O3 . HCl. MW: 330.3 . 36.5. Synthetic Fluorescent dye. Fluorophore standard that is widely used in enzyme assay systems. Precursor for a variety of R110-based enzyme substrates for flow cytometric measurements. Used as a calibration standard for R110-based enzyme substrates. Compared to AMC and AFC enzyme substrates, fluorogenic R110 substrates are generally more sensitive, giving longer absorption and fluorescence wavelength than AMC and AFC substrates. Spectral data: lambdaex 498nm| lambdaem 520nm in methanol.
