GST antibodies are immunological tools designed to detect GST-tagged proteins or endogenous GST enzymes involved in detoxification and cellular protection. While GSTF14 is not explicitly documented in the provided sources, the following insights apply broadly to GST-targeting antibodies:
Function: GST antibodies recognize glutathione S-transferases, which catalyze the conjugation of glutathione to electrophilic substrates, aiding in toxin metabolism and oxidative stress response .
Structure: These antibodies typically target conserved epitopes within GST domains, such as the N-terminal thioredoxin fold or C-terminal helical domain .
The search results highlight several GST-targeting antibodies with validated applications:
Skin Carcinogenesis: GSTA4 deficiency increased susceptibility to tumor promotion by 12-O-tetradecanoylphorbol-13-acetate (TPA) in mice, with 0.8 tumors/mouse vs. 0.4 in wild-type controls (P = 0.007) .
Neuromyelitis Optica: Anti-AQP4 antibodies (structurally similar to GST antibodies) showed 99.27% specificity in diagnosing neuromyelitis optica spectrum disorders .
Western Blot: GSTP1 antibodies detected a 25 kDa band in human placenta lysates under reducing conditions .
Immunohistochemistry: GSTA4 antibodies localized to epidermal layers in TPA-treated mouse skin .
Cross-Reactivity: Some GST antibodies (e.g., anti-GST Tag #2622) may cross-react with GST isoforms across species due to conserved epitopes .
Assay Optimization: Antibody performance varies by sample preparation; for example, GSTA4 activity assays require purified epidermal lysates and spectrophotometric monitoring at 224 nm .
While GSTF14-specific data remain absent in the analyzed literature, advancements in GST antibody engineering (e.g., Fc region modifications to enhance half-life ) suggest potential pathways for developing novel GSTF-targeting reagents. Researchers should consult specialized databases (e.g., UniProt, Antibody Registry) for emerging tools.
