Product Overview
This rabbit polyclonal antibody detects 4-aminobutyrate aminotransferase, mitochondrial (gene ABAT) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF and Western blot. The predicted molecular weight is 56.4 kDa, and the supplier reports an observed band at about 54 kDa.
4-Aminobutyrate aminotransferase (ABAT, GABA-T) is a mitochondrial enzyme that breaks down the inhibitory neurotransmitter GABA to succinate semialdehyde. By controlling GABA levels in the brain it is an important target in neuroscience, and it is inhibited by the antiepileptic drug vigabatrin.

Immunogen
Recombinant human ABAT fragment (Lys388–Lys500), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 93.9% and 94.5%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places 4-aminobutyrate aminotransferase, mitochondrial in the mitochondrion matrix. Tissue expression noted by UniProt (human): Liver > pancreas > brain > kidney > heart > placenta. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
