Description

Glutathione S-transferase omega-1 (GSTO1) plays a distinctive role in cellular redox homeostasis, functioning not only as a member of the glutathione transferase superfamily but also as a glutathione-dependent dehydroascorbate reductase. This dual functionality positions GSTO1 as a key player in oxidative stress responses and ascorbate recycling pathways, making it a valuable target for researchers investigating metabolic regulation, detoxification mechanisms, and cellular stress responses.

This recombinant monoclonal antibody, generated from clone 2C7, offers the reproducibility and consistency that demanding experimental workflows require. Because the antibody sequence is defined and production occurs in a controlled recombinant system, you can expect reliable performance across experiments and between lots, eliminating the variability often encountered with traditional hybridoma-derived antibodies. The rabbit IgG format, raised against a synthetic peptide derived from human GSTO1, provides high specificity for your target.

Validation across multiple applications gives you flexibility in experimental design. Western blot analysis demonstrates robust detection of GSTO1 at the expected 28 kDa band across a diverse panel of human cell lines including Jurkat, PC3, Raji, K562, HeLa, A549, and HepG2, confirming reliable performance in both hematological and solid tumor models. Immunohistochemistry validation in paraffin-embedded human liver tissue and liver cancer specimens shows clear staining using citrate buffer antigen retrieval, while immunofluorescence staining in HepG2 cells reveals distinct cytoplasmic localization patterns when counter-stained with DAPI.

Whether you're examining GSTO1 expression changes in disease states, investigating its role in drug metabolism, or characterizing cellular stress responses, this antibody provides a dependable tool for protein detection and localization studies in human samples.
