Oxidative stress - kits to measure the anti-oxidative potential of samples
Figure 1: Oxidative stress and related diseases.

Oxidative stress can lead to diverse pathophysiological changes in the body. Neurodegenerative diseases such as Parkinson and Alzheimer are linked to oxidative stress, as well as several cancers and diseases such as chronic fatigue syndrome, fragile X syndrome, heart and blood vessel disorders, heart attack, heart failure, and atherosclerosis (for an overview see Fig. 1). In this post, let’s look at some convenient kits to measure the anti-oxidative potential of your samples!

New: QuicGSH3.0 – a fluorescent probe to quantify intracellular glutathione

25/05/2018 by Frédéric Samazan No Comments

Glutathione (GSH) is a tri-peptide (Glutamic acid, Cystein and Glycine) present in cells, showing an antioxidant effect allowing the reduction and the removal of Reactive Oxygen Species (ROS) and Peroxide from the cell. The new QuicGSHS3.0 probe from Goryo Chemicals will allow you to easily quantify intracellular concentration of GSH by Fluorescent Live cell Imaging.

Mitochondria keep cells “healthy” in their environment. In this post, we’ll take a look at a new fluorescent assay for the monitoring of mitophagy, a process aimed at clearing damaged or superfluous mitochondria by autophagy, in mammalian cells.

Measure antioxidative capacities of your samples

26/11/2014 by Ali El Baya, PhD No Comments

Free radicals and Reactive Oxygen Species (ROS) are highly reactive molecules generated by normal cellular processes, environmental stress, and UV irradiation. ROS react with numerous cellular components damaging DNA (but also carbohydrates, proteins, and lipids) and cause cellular and tissue injury. Measuring antioxidative capacities of biological fluids, cells, and tissue such active molecules is becoming more and more important in the pharmaceutical industry and in academic laboratories. Let’s focuse here on 2 robust methods.
