Our Abpromise guarantee covers the use of ab81432 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 56 kDa (predicted molecular weight: 56 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay 1/12500.

IHC-Fr 1/100.


  • FunctionCatalyzes the conversion of gamma-aminobutyrate and L-beta-aminoisobutyrate to succinate semialdehyde and methylmalonate semialdehyde, respectively. Can also convert delta-aminovalerate and beta-alanine.
  • Tissue specificityLiver > pancreas > brain > kidney > heart > placenta.
  • Involvement in diseaseDefects in ABAT are a cause of gamma-aminobutyrate transaminase deficiency (GABA-AT deficiency) [MIM:613163]. The phenotype of this deficiency includes psychomotor retardation, hypotonia, hyperreflexia, lethargy, refractory seizures, and EEG abnormalities.
  • Sequence similaritiesBelongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
  • Cellular localizationMitochondrion matrix.

Anti-ABAT antibody images

  • ab81432 staining ABAT in zebrafish retina sections by IHC-Fr. The tissue was fixed with paraformaldehyde and an antigen retrieval step was performed with sodium citrate pH 6. Blocking of the sample was done with 5% BSA in PBS containing 01% Tween 20 and 0.5% Triton X, for 60 minutes at 23°C, followed by staining with ab81432 at 1/100 in blocking solution for 16h at 4°C. An alexa 488 conjugated goat anti-rabbit polyclonal antibody at 1/1000 was used as the secondary antibody. Nuclei are stained in blue with DAPI. ABAT I expression can be observed in amacrine cells (in green).
