Plant oxidative stress antibody set, 20 % off until end of March

Oxidative stress response in plants involves a complex network of proteins that work together to mitigate the damage caused by reactive oxygen species (ROS), such as superoxide radicals, hydrogen peroxide, and hydroxyl radicals. Below is a list of the main proteins involved in this process:

• Superoxide dismutase (SOD): Enzyme that catalyzes the dismutation of superoxide radicals into oxygen and hydrogen peroxide. There are different isoforms of SOD found in various cellular compartments, such as cytosol, mitochondria and chloroplast.
• Catalase (CAT): Enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen. It is primarily located in peroxisomes and helps neutralize excess hydrogen peroxide, generated during oxidative stress.
• Ascorbate peroxidase (APX): Enzyme that uses ascorbate as a reducing agent to scavenge hydrogen peroxide and convert it into water, while oxidizing ascorbate to monodehydroascorbate. This enzyme is crucial for maintaining the redox balance in chloroplasts and other cellular compartments.
• Glutathione peroxidase (GPX): Enzyme that utilizes glutathione (GSH) as a cofactor to reduce hydrogen peroxide and lipid hydroperoxides to their corresponding alcohols. It plays a significant role in protecting cells from oxidative damage by ROS.
• Glutathione S-transferases (GSTs): Family of enzymes that catalyze the conjugation of glutathione to a wide range of electrophilic compounds, like lipid peroxides and xenobiotics. They are involved in both detoxification processes and in the regulation of cellular redox status.
