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

VGAT or VIAAT is the GABA and glycine transporter in the membrane of synaptic vesicles

pH-sensitive probe fluorescent only under acidic conditions

Rabbit polyclonal purified antibody
Cat. No.: 131 103CpH
Amount: 50 µg
Price: $780.00
Cat. No. 131 103CpH 50 µg specific antibody, lyophilized. Affinity purified with the immunogen, fluorescence-labeled with CypHer5E.

CypHer5E® is a pH-sensitive dye, fluorescent only after antibody internalization at the acidic pH of the lumen of the synaptic vesicle. CypHer5E® can be detected with the filter sets for Cy5®.

CypHer5E®: λex 647 nm / λem 667 nm

 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.

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.
