γ-aminobutyric acid (GABA) conjugated to BSA.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% BSA and 15 mM sodium azide.


Expression of GABA in neucortical cells harvested from the brains of E19 day old rat embyros was detected by immunofluorescence using rabbit anti-GABA antibody. Triple IF staining was performed with the anti-GABA antibody and two anti-GAD antibodies. Expression of GABA was analyzed in cells isolated from the pallium of various animals including rats, mice, rabbits, guinea pigs, and lizards by immunohistochemistry. IHC was performed using rabbit anti-GABA antibody at 1:1000 diluted in a solution of 0.01M PBS ph 7.4 + 0.5% triton-x100.

Rabbit anti-GABA antibody has been used for electron microscopy analysis in rat hippocampal tissues at a dilution of 1:4000. The antibody has also been used for immunocytochemistry applications at dilutions ranging from 1:100-1:750 in Drosophila and Periplaneta americana brain cells.

General description

GABA (γ-Aminobutyric acid) is the major inhibitory neurotransmitter in the central nervous system and also functions as a neuromodulator in some peripheral tissues. GABA is present in non-nervous structures, and plays an essential role in the modulation of heart rate decreases, blood pressure, and respiratory depression. GABA facilitates neuronal inhibition by interacting with GABA/benzodiazepine receptor and opening an integral chloride channel. Rabbit anti-GABA antibody shows positive binding with GABA and GABA-KLH in a dot blot assay, and exhibits negative binding with BSA.
