|Datasheet||Product citations||Protocols||Customer reviews|
thioredoxin fusion of 58 amino acid region between Ser at position 175 and the C-terminal Ala of Arabidopsis thaliana GPX7 accession At4g31870 has been used for antibody production
25 | 20 kDa
This antibody is recognizing Arabidopsis thaliana GPX (two chloroplastic isoforms). Antibody has also a weak cross-reactivity to cytosolic forms, therefore work on isolated chloroplasts is recommended.
GPX belongs to the group of enzymes that protect cells against oxidative damage generated by reactive oxygen species (ROS). Glutathione peroxidase catalyzes the reduction of H2O2, organic hydroperoxides, and lipid peroxides in the presence of glutathione, the hydrogen donor. Activity of the enzyme can be increased under environmental stress. Immunogen: Peptide target chosen from C-terminal of two chloroplastic isoforms of Arabidopsis thaliana GPX.
