详细信息:Oxidative stress has been found to play a key role in a number of pathological disorders. To aid researchers studying this phenomenon Millipore has developed the FlowCellect™ Oxidative Stress Characterization Kit. This kit contains the chemical and immunological reagents necessary to detect carbonyl groups introduced onto proteins by reactive oxygen species (ROS). The test method involves derivatization of protein carbonyl groups with 2,4-dinitrophenylhydrazine (DNPH). This chemical reaction results in proteins being covalently coupled to DNP at their carbonyl sites. The DNP-derivatized proteins are then incubated with a FITC conjugated monoclonal antibody that specifically binds to the DNP moiety. Subsequent detection with a bench-top Guava EasyCyte™ Plus flow cytometer allows quantification of the extent of oxidative stress within cells. Although the assay and all of the kit components were optimized using a Guava instrument, any flow cytometer can be utilized provided it contains a blue laser (488 nm) light source.
