Invitrogen™ CellROX™ Green Flow Cytometry Assay Kit

Invitrogen™ CellROX™ Green Flow Cytometry Assay Kit

The CellROX™ Green Flow Cytometry Assay Kit enables the flow cytometric detection of reactive oxygen species (ROS) in live cells. The kit includes the novel, fluorogenic CellROX™ Green Reagent, as well as SYTOX™ Red Dead Cell Stain, N-acetyl cysteine (an antioxidant, for negative control), and tert-butyl hydroperoxide solution (TBHP, an inducer of ROS).

The CellROX™ Green Detection Reagent is cell-permeable and non-fluorescent or very weakly fluorescent while in the reduced state. Upon oxidation, the reagent binds DNA and exhibits a strong fluorogenic signal that has absorption/emission maxima of 508/525 nm and remains localized to the nucleus and cytoplasm. When used together with the included SYTOX™ Red Dead Cell Stain, oxidatively stressed and nonstressed cells are reliably distinguished from dead cells by flow cytometry.

Features

• Fluorogenic probe formulated for flow cytometry that is oxidized in the presence of ROS
• Multicolor compatibility—minimal overlap with fluorophores excited by other laser lines, allowing easy multiplexing with other reagents
• Simple protocol—cells can be stained in complete media or other appropriate buffer, no need for serum free media
