FluoTag®-X2 anti-Synaptotagmin 1 (A51)

Cat No: N4302 Category:


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.

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.

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