GSTM1 Antibody

Overview

Members of the glutathione S-transferase (GST) family of proteins function in the detoxification of xenobiotics to protect cells against toxicant-induced damage. There are eight families of GST proteins, each of which are composed of proteins that have a variety of functions throughout the cell. The GSTM proteins (GSTM1-GSTM5 in human and GSTM1-GSTM7 in mouse) are members of the mu class of enzymes that conjugate with glutathione and function in the detoxification of carcinogens, environmental toxins and products of oxidative stress. The genes encoding the mu class of enzymes are organized in a gene cluster on chromosome 1p13.3 and are known to be highly polymorphic. These genetic variations can change an individual's susceptibility to carcinogens and toxins as well as affect the toxicity and efficacy of certain drugs. Null mutations of this class mu gene have been linked with an increase in a number of cancers, likely due to an increased susceptibility to environmental toxins and carcinogens. Multiple protein isoforms are encoded by transcript variants of this gene.

This anti-GSTM1 antibody is supplied as Purified (Mouse, Monoclonal (mouse origin), clone CPTC-GSTMu1-3, Mouse IgG1, kappa, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.

Key elements and design rationale

• Target: GSTM1
• Format: Purified
• Localization: Cytoplasmic
• Species reactivity: Human
• Applications (listed): WB, IHC-P
• Conjugate: Unconjugated
• Clone and antibody class: Monoclonal (mouse origin), clone CPTC-GSTMu1-3, Mouse IgG1, kappa

Because antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.

Biological background

GSTM1 is referenced in public gene/protein resources (e.g., UniProt and NCBI Gene), which provide curated names/synonyms, protein features, and pathway context. When designing assays, consider potential isoforms, post-translational modifications, and cell-type specific expression that may influence observed signal.

Research relevance and current trends

• Profiling GSTM1 expression across model systems, perturbations, and time points to support mechanistic hypotheses.
• Combining antibody-based detection with multi-omics or imaging readouts to link GSTM1 signal with phenotype.
• Using well-matched controls (isotype controls, genetic perturbations, or independent reagents) to strengthen interpretation of target-associated signal.

Common research applications

• WB
• IHC-P

Use the listed applications as a starting point and tailor experimental design to your sample type and readout requirements.

Notes for experimental interpretation

• Specificity considerations: closely related family members, isoforms, or PTMs can affect apparent specificity; confirm with independent approaches when critical.
• Controls: include negative controls and, when feasible, genetic or pharmacologic perturbations to support target attribution in your system.
• Species and sample context: differences in sequence, expression, fixation, or extraction conditions can change signal behavior across models.

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).
