Product Overview
This rabbit polyclonal antibody detects glutathione S-transferase A1 (gene GSTA1) in human, mouse and rat samples and is validated for ELISA, IHC and Western blot. The predicted molecular weight is 25.6 kDa, and the supplier reports an observed band at about 26 kDa.
Glutathione S-transferase A1 (GSTA1) is an alpha-class GST that attaches glutathione to a wide range of electrophilic drugs, toxins and endogenous compounds, making them easier to excrete. It also shows glutathione peroxidase activity toward lipid hydroperoxides and can isomerize steroid precursors. GSTA1 is abundant in liver and is studied in detoxification and drug metabolism.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL |
| ELISA (capture antibody) | 1–5 µg/mL |
Samples with a confirmed band (WB): human HepG2 cells, human hcct tissue, human hccp tissue, human HUH-7 cells, rat liver tissue, rat RH35 cells, mouse liver tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human lung cancer tissue, human liver cancer tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Immunogen
Recombinant human GSTA1/A2/A3/A4/A5 fragment (Ala2–Phe222), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places glutathione S-transferase A1 in the cytoplasm. Tissue expression noted by UniProt (human): Liver. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
