FluoTag®-X2 anti-Synaptotagmin 1 A51 (SYT1) is an alpaca single-domain antibody (sdAb) that recognizes specifically the cytoplasmic domain of murine Synaptotagmin 1 with high affinity and specificity.
Synaptotagmin 1 (Syt1) belongs to a family with 17 members. Synaptotagmins are all single-pass transmembrane proteins containing two domains binding to calcium at their intracellular portion. Synaptotagmin 1 is enriched at the pre-synaptic boutons on axon terminals, associated with synaptic vesicles, and is implicated in triggering vesicle fusion and neurotransmitter release upon a local increase of calcium concentration.
Our nanobody recognizes strongly and specifically the cytosolic portion of Syt1.
FluoTags are directly conjugated to fluorophores, however, they can be equipped with a single fluorophore for more quantitative readouts (FluoTag-Q), with two fluorophores per single-domain antibody (FluoTag-X2), and we also developed a blend of two sdAbs bindings simultaneously the target proteins and each bearing two fluorophores, decorating the target protein with 4 fluorophores in total (FluoTag-X4). For more detailed information on the FluoTags, please check our Technology Section.
|Dilution:||1:500 (corresponding to 5 nM final concentration)|
|Targets:||Synaptotagmin 1 (cytosolic)|
|Specificity:||Recognizes the cytosolic domain of rat and mouse Synaptotagmin 1 (other species not tested).|
|Formulation:||The single sdAb clone was lyophilized from PBS pH 7.4, containing 2% BSA (US-Origin). Reconstitute with 200 µL of 50 % glycerol in deionized water. We recommend including 0.1 % sodium azide as a preservative if applicable. When reconstituted with 200 µl, the concentration of single-domain antibody is 2.5 µM|
|Storing:||Vials containing lyophilized protein can be stored at 4°C for 6 months. We recommend reconstituting the protein with 50 % sterile glycerol including 0.1 % sodium azide as preservative if applicable. Minimize the number of freeze-thaw cycles by aliquoting the reconstituted protein. Long term storage at -80 °C for up to 6 months. Working aliquots can be stored at -20°C for up to 4 weeks. We do not recommend storing the reconstituted protein at 4 °C.|
This Product is not recommended to be used to detect proteins in Western Blott, sdAbs tend to recognize native/folded protein mainly.
