PA1-18279 detects Glutathione Peroxidase 1 from human and rat samples.
PA1-18279 has been successfully used in immunohistochemistry (paraffin and frozen), ELISA and Western blot procedures.
The PA1-18279 immunogen is a synthetic peptide corresponding to residues R(175) R Y S R R F Q T I D I E P D I E A L L(194) of human glutathione peroxidase 1 ( GPx-1), conjugated to diphtheria toxin.
After reconstitution keep aliquots at -20°C for a higher stability, and at 4°C with an appropriate antibacterial agent. Avoid freeze/thaw cycles. Glycerol (1:1) may be added for an additional stability.
Reconstitute with 100 µL of distilled water.
Glutathione peroxidases (Gpxs) are ubiquitously expressed proteins which catalyze the reduction of hydrogen peroxides and organic hydroperoxides by glutathione. There are several isoforms which differ in their primary structure and localization. The classical cytosolic/mitochondrial GPx1 (cGPx) is a selenium-dependent enzyme, first of the GPx family to be discovered. GPx2, also known as gastrointestinal GPx (GI-GPx), is an intracellular enzyme expressed only at the epithelium of the gastrointestinal tract. Extracellular plasma GPx (pGPx or GPx3) is mainly expressed by the kidney from where it is released into the blood circulation. Phospholipid hydroperoxide GPx4 (PH-GPx) expressed in most tissues, can reduce many hydroperoxides including hydroperoxides integrated in membranes, hydroperoxy lipids in low density lipoprotein or thymine. All mammalian GPx family members, except for the recently described Cys containing GPx3 and epididymis-specific secretory GPx (eGPx or GPx5) isoforms, possess selenocysteine at the active site.
