Scientific background

The superfamily of amino acid transporters includes SLC32, SLC36 and SLC38 families. SLC32 has only one member, the vesicular inhibitory amino acid transporter (VIAAT) or vesicular GABA transporter (VGAT)1.

VGAT is responsible for the uptake of GABA and glycine in exchange of protons, and their release from nerve terminals1.

The transporter is organized into ten membrane spanning domains, a cytosolic N-terminus and a luminal C-terminal tail2. In many regions in the brain, where it is expressed, it is found constitutively phosphorylated, although the biological significance is currently unknown3.

VGAT is expressed on synaptic vesicles of GABAergic and glycinergic neurons4-6. The transporter is also detected in the pituitary gland and in the pancreas7,8.

Anti-Vesicular GABA Transporter (VGAT) Antibody (#AGT-005) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunohistochemistry, and immunocytochemistry applications. It has been designed to recognize VGAT from human, mouse, and rat samples.

Anti-Vesicular GABA Transporter (VGAT)-ATTO Fluor-594 Antibody (#AGT-005-AR) is directly labeled with an ATTO-594 fluorescent dye. ATTO dyes are characterized by strong absorption (high extinction coefficient), high fluorescence quantum yield, and high photo-stability. The ATTO-594 fluorescent label belongs to the class of Rhodamine dyes and can be used with fluorescent equipment typically optimized to detect Texas Red and Alexa-594. Anti-Vesicular GABA Transporter (VGAT)-ATTO Fluor-594 Antibody has been tested in immunohistochemical applications and is specially suited to experiments requiring simultaneous labeling of different markers.
