Key elements and design rationale

• Antibody format: Rabbit Polyclonal Rabbit IgG
• Immunogen / epitope context: E. coli-derived human GSTM3 recombinant protein (Position: E93-Q206). (reported region: E93-Q206).
• Molecular weight context: reported MW: 27 kDa; calculated MW: 27 kDa
• Reactivity: Human,Mouse
• Applications: ELISA, IHC, WB

As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.

Biological background

glutathione S-transferase mu 3. Glutathione S-transferase M3 (brain), also known as GSTM3, is an enzyme which in humans is encoded by theGSTM3 gene. Cytosolic and membrane-bound forms of glutathione S-transferase are encoded by two distinct supergene families. At present, eight distinct classes of the soluble cytoplasmic mammalian glutathione S-transferases have been identified: alpha, kappa, mu, omega, pi, sigma, theta and zeta. This gene encodes a glutathione S-transferase that belongs to the mu class. The mu class of enzymes functions in the detoxification of electrophilic compounds, including carcinogens, therapeutic drugs, environmental toxins and products of oxidative stress, by conjugation with glutathione. 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. Mutations of this class mu gene have been linked with a slight increase in a number of cancers, likely due to exposure with environmental toxins. Functional note: Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. May govern uptake and detoxification of both endogenous compounds and xenobiotics at the testis and brain blood barriers. Reported localization: Cytoplasm. Expression/tissue context: Testis and brain.

Research relevance and current trends

• Cancer: Researchers commonly examine how GSTM3 relates to this theme using model systems and orthogonal readouts.
• Drug Metabolism: Researchers commonly examine how GSTM3 relates to this theme using model systems and orthogonal readouts.
• Metabolic Signaling Pathways: Researchers commonly examine how GSTM3 relates to this theme using model systems and orthogonal readouts.

Common research applications

• Western blotting: compare relative GSTM3 levels across conditions; band patterns may reflect isoforms and processing.
• IHC/IHC-F: assess spatial distribution of GSTM3 across tissue regions and cell types using matched controls.
• ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.

Notes for experimental interpretation

• Specificity notes: No cross reactivity with other proteins.
• Cross-reactivity: No cross-reactivity with other proteins.
• Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
• Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
