VGluT1 sdAb - FluoTag-X2 - N1602-At488-L

VGluT1 is a glutamate transporter in the membrane of synaptic vesicles

 

This product was developed by   

NanoTag-Biotechnologies

Camelid single domain antibodies (sdAbs) consist only of one antigen binding site of an Alpaca heavy chain antibody. With only ~15 kDa, these Tags are about 10-times smaller than conventional IgG antibody molecules.

Camelid single domain antibody

Cat. No.: N1602-At488-L
Amount: 200 µl
Price: $515.00
Cat. No. N1602-At488-L 200 µl purified antibody, lyophilized from PBS, fluorescence-labeled with ATTO® 488.

For many of the fluorescence labeled antibodies conjugated to ATTO® dyes from ATTO-TEC the established fluorescence detection systems can be used.
ATTO® 488: λex 500 nm / λem 520 nm
ATTO® 550: λex 554 nm / λem 576 nm
ATTO® 647N: λex 646 nm / λem 664 nm

ATTO®488, ATTO®647N and ATTO®594 dyes are suitable for Stimulated Emission Depletion (STED) microscopy which allows higher resolution imaging compared to confocal laser scanning microscopy.
ATTO®488 and ATTO®594 are also recommended for PALM and dSTORM high resolution microscopy.

Albumin was added for stabilization. For reconstitution add 200 µl H2O. 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 glutamate transporter 1 VGLUT 1, also referred to as BNPI and SLC17A7, was originally identified as a brain specific phosphate transporter. Like the related VGLUT 2, VGLUT 1 is both necessary and sufficient for uptake and storage of glutamate and thus comprises the sole determinant for a glutamatergic phenotype. Both VGLUTs are different from the plasma membrane transporters in that they are driven by a proton electrochemical gradient across the vesicle membrane.
VGLUT 1 and VGLUT 2 show complementary expression patterns. Together, they are currently the best markers for glutamatergic nerve terminals and glutamatergic synapses.

 

Unlabeled variants and several modifications of sdAbs like biotin, fluorophore or DBCO conjugation are available.


In FluoTag®-X2 two fluorophore molecules are site-specifically coupled to each FluoTag molecule. Therefore, the reagent simultaneously targets two  fluorophores to the protein of interest, which ensures up to two-fold („2X“)-brighter signals. Owing to the small size of the FluoTags, the distance between the target epitope and each fluorophore is ~ 3 nm.
In comparison to detection systems using conventional antibodies, FluoTag-X can thus improve the localization accuracy by 10-15 nm. Both features - superior brightness and precise fluorophore placement - render the FluoTag-X products excellent tools for all microscopy techniques.
