VGAT antibody luminal domain - 131 103C3 K.O.

VGAT or VIAAT is the GABA and glycine transporter in the membrane of synaptic vesicles
Rabbit polyclonal purified antibody
Cat. No.: 131 103C3
Amount: 50 µg
Price: $780.00
Cat. No. 131 103C3 50 µg specific antibody, lyophilized. Affinity purified with the immunogen, fluorescence-labeled with Cyanine 3.

Fluorescence labeled antibodies conjugated to Cyanine dyes are well suited for standard epi-fluorescence setups and confocal microscopy.

Cyanine 2: λex 492 nm / λem 508 nm
Sulfo-Cyanine 3: λex 554 nm / λem 568 nm
Sulfo-Cyanine 5: λex 649 nm / λem 667 nm

Cyanine 5 dyes are well suited for STORM high resolution microscopy.
Sulfo-Cyanines are highly water soluble and allow a higher labeling degree and consequently brighter conjugates.

 Albumin was added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Either add 1:1 (v/v) glycerol, then aliquot and store at -20°C until use, or store aliquots at -80°C without additives.
Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye.

ICC
Background
The vesicular GABA transporter VGAT is responsible for uptake and storage of GABA and glycine by synaptic vesicles in the central nervous system. For this reason it is frequently referred to as the vesicular inhibitory aminoacid transporter VIAAT. It is different from the plasma membrane transporters in that it is driven by a proton electrochemical gradient across the vesicle membrane. So far, only one isoform is known. VGAT is currently the best marker for inhibitory nerve terminals.
