Clear

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.

Shipping: Ambient temperature
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.
Protocols:

This Product is not recommended to be used to detect proteins in Western Blott, sdAbs tend to recognize native/folded protein mainly.

Look at detailed protocols in our Resource Section.
