Learning Center – Protein Oxidation

Learning Center – Protein Oxidation

Redox metabolism and redox regulation of proteins have revolutionized biomedical research and are fast advancing towards clinical implementation 1. At the core of these concepts is the reaction of protein cysteine thiols with electrophiles or their oxidation, which influence the stability, structure and/or function of proteins (e.g., resistance to drugs) 2,3. Therefore, the study of protein modifications at cysteine and other redox sensitive sites is critical and needs to be conducted with a high level of precision.

Our portfolio of chemical reagents includes a series of compounds for applications compatible with most common downstream analytical technologies such as imaging, flow cytometry, Western blot, and mass spectrometry. Examples of reagents for studying protein sulfenylation, a key protein redox modification at reactive cysteines, and typical workflows are included below 4-.11.  These can be found here [link to Market All Products] along with reagents for other redox modifications and redox modifiers (e.g., ROS generators and quenchers).
