SUGCT Antibody

What is SUGCT and why is it important in scientific research?

SUGCT (Succinate--hydroxymethylglutarate CoA-transferase) is a mitochondrial enzyme that catalyzes the succinyl-CoA-dependent conversion of glutarate to glutaryl-CoA. It plays a critical role in metabolic pathways supporting cell growth and survival, making it relevant for research on metabolic disorders, cancer, and neurodegenerative diseases . The enzyme can utilize various dicarboxylic acids as CoA acceptors, with preferences for glutarate, succinate, adipate, and 3-hydroxymethylglutarate . Recent research has identified SUGCT as a potentially important target in Glutaric Aciduria Type 1 (GA1), with the hypothesis that its inhibition could decrease neurotoxic metabolite buildup in this serious inborn error of metabolism . When designing experiments involving SUGCT, researchers should consider its mitochondrial localization and its role in amino acid metabolism and reactive oxygen species management.

What are the common applications for SUGCT antibodies?

SUGCT antibodies are versatile research tools applicable across multiple experimental platforms. The most validated applications include:

For optimal results in Western blot applications, researchers should validate the appropriate dilution for their specific experimental conditions using positive control samples such as HepG2 cell lysates, mouse liver extracts, or rat kidney extracts . When performing immunohistochemistry, antigen retrieval methods should be optimized depending on the fixation method used. SUGCT antibodies enable researchers to effectively detect and analyze the enzyme in various cell types, making them essential for studies in metabolism, mitochondrial function, and oxidative stress responses .

What species reactivity do SUGCT antibodies typically exhibit?

Commercial SUGCT antibodies demonstrate variable cross-reactivity profiles. Based on available research reagents, many SUGCT antibodies show reactivity to human SUGCT protein, with some exhibiting cross-reactivity with mouse and rat orthologs . When selecting an antibody:

• For human sample analysis, multiple validated options exist with confirmed specificity

• For mouse models, verify the specific epitope recognition, as some antibodies recognize the human sequence corresponding to amino acids 1-250 of human SUGCT (NP_001180240.1)

• For rat studies, fewer validated options exist, so preliminary validation experiments are strongly recommended

When working with less common model organisms, researchers should perform validation experiments to confirm cross-reactivity or consider custom antibody development against species-specific sequences. Epitope sequence alignment analysis between target species can help predict potential cross-reactivity before experimental validation.

How should SUGCT antibodies be stored and handled for optimal performance?

Proper storage and handling of SUGCT antibodies are critical for maintaining their performance and extending their usable lifespan. Based on manufacturer recommendations:

• Long-term storage: Upon receipt, store antibodies at -20°C or -80°C to prevent degradation . Avoid repeated freeze-thaw cycles by aliquoting the antibody into single-use volumes.

• Working solution preparation: When preparing dilutions, use sterile buffers and aseptic technique to prevent microbial contamination.

• Buffer considerations: Most SUGCT antibodies are supplied in PBS with 0.02% sodium azide and 50% glycerol at pH 7.3 . This formulation helps maintain stability during freeze-thaw cycles.

• Handling precautions: Sodium azide is toxic and can form explosive compounds with plumbing materials. Always flush with large volumes of water when disposing of solutions containing sodium azide.

• Performance monitoring: Include positive controls in each experiment to verify antibody performance over time. Diminished signal intensity may indicate antibody degradation.

By following these storage and handling protocols, researchers can maximize the reliability and reproducibility of their experimental results using SUGCT antibodies.
