S-Glutathionylated Protein Detection Assay Kit provides a convenient method for the direct visualization of S-glutathionylated proteins in whole (permeabilized) cells by flow cytometry and microscopy as well as avidin overlay analysis. Storage: -20 °C . This cell-based assay starts with the modification of protein free-thiols groups followed by enzymatic cleavage of any protein-S-glutathione (PSSG) adducts present in the sample.
Glutathione (GSH) is a tripeptide (γ-glutamylcysteinylglycine) widely distributed in both plants and animals. The concentration of GSH ranges from a few micromolar in plasma to several millimolar in tissues such as liver. Protein S-glutathionylation (PSSG) may modify the activity of a large number of cell proteins, including metabolic, structural, cytoskeletal, and signaling proteins. GSH derivatives, and differential labeling systems based on the “Biotin-Switch” method.
Reagents are provided to test three sets of 10 samples (most convenient) or up to thirty samples total at once if desired. Protein S-glutathionylation (PSSG) may modify the activity of a large number of cell proteins, including metabolic, structural, cytoskeletal, and signaling proteins. PSSG detection methods can employ GSH adduct antibodies, GSH derivatives, and differential labeling systems based on the “Biotin-Switch” method.
