  • Product overview

    Cellular ROS/RNS Assay Kit (ab139473) is designed to directly monitor real time reactive oxygen and/or nitrogen species (ROS/RNS) production in live cells using fluorescence microscopy. The kit includes three fluorescent dye reagents: NO Detection Reagent (Red), Oxidative Stress Detection Reagent (Green) for total ROS detection, and Superoxide Detection Reagent (Orange). It also includes positive controls, pyocyanin and L-arginine, which are common inducers of ROS and NO production, respectively, as well as negative controls, N-acetyl-L-cysteine and c-PTIO (common scavengers of ROS and NO, respectively). Through the combination of the three detection probes with a set of specific inhibitors and activators, this kit enables discrimination among superoxide, nitric oxide and peroxynitrite.

Question



I need some kit for my experimental work like Lipid peroxidation, NADPH oxidase & Reactive oxygen spices. in which these all will work on rat or not.because i will do my work on rat and will take their blood and tissue homogenate for further study of these parameters. these all kits having maximum 1 year expiry or not.

Answer



I double checked and unfortunately, have confirm that we do not have a kit for measuring NADPH oxidase in our catalog at the moment. We do offer ab65349 which is a NADP/NADPH Assay Kit:

I can recommend the following products

ab118970 (Lipid Peroxidation (MDA) Assay Kit)

ab139473 (Cellular ROS/RNS Detection Assay Kit)

https://www.abcam.com/index.html?datasheet=139473 (or use the following: https://www.abcam.com/index.html?datasheet=139473).

ab139476 (Cellular ROS/Superoxide Detection Assay Kit)

https://www.abcam.com/index.html?datasheet=139476 (or use the following: https://www.abcam.com/index.html?datasheet=139476).

ab139473, Cellular ROS/RNS Detection Assay Kit for microscopy is used for monitoring reactive oxygen and/or nitrogen species (ROS/RNS) in live cells.

This kit can be used for discriminates among superoxide, nitric oxide and peroxynitrite by fluorescence microscopy. The kit includes three fluorescent dye reagents.

ab139476, Cellular ROS/Superoxide Detection Assay Kit: Total ROS/Superoxide detection kit is designed to directly monitor real time reactive oxygen species (ROS) production in live cells using fluorescence microscopy or flow cytometry. The kit includes two fluorescent dyes as major components: Oxidative Stress Detection Reagent (Green) for total ROS detection reagent and Superoxide Detection Reagent (Orange).

This kit distinguishes between different reactive species, such as hydrogen peroxide, peroxynitrite and hydroxyl radicals.

I can confirm that all our kits are covered by our Abpromise guarantee for m12 month if they are unopened and stored as instructed in the protocol booklet. Please note that some reagents in the kits can only be stored short term if they are opened or reconstituted.

Question

My sample is moving cells - spermatozoa. So it is not easy to take a good picture without fixing the sample. Are the three dyes compatible with fixation of the cells (i.e, 4% PFA or other)? Would the microscopic observation work with fixed cells to reflect the changes of ROS (or RNS) levels?

Answer

The lab says fixation will cause the dyes to leak from the cells. I think the assumption is that fixation may damage cell membranes. I did find a paper which describes fixation using methanol or acetic acid, after staining with a DCFDA derivative. DCFDA is the reagent that stains ROS in the kit ab113851, and I suspect that it is the green dye in the other two kits, the ROS/NOS and superoxide assays, though our source for those kits has not confirmed.
