Synaptotagmin1 antibody luminal domain - 105 103C2

Synaptotagmin1 is a Ca2+-sensor on synaptic vesicles that triggers neurotransmitter release
Rabbit polyclonal purified antibody
Cat. No.: 105 103C2
Amount: 50 µg
Price: $480.00
Cat. No. 105 103C2 50 µg specific antibody, lyophilized. Affinity purified with the immunogen, fluorescence-labeled with Cyanine 2.

Fluorescence labeled antibodies conjugated to Cyanine dyes are well suited for standard epi-fluorescence setups and confocal microscopy.

Cyanine 2: λex 492 nm / λem 508 nm
Sulfo-Cyanine 3: λex 554 nm / λem 568 nm
Sulfo-Cyanine 5: λex 649 nm / λem 667 nm

Cyanine 5 dyes are well suited for STORM high resolution microscopy.
Sulfo-Cyanines are highly water soluble and allow a higher labeling degree and consequently brighter conjugates.

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
Synaptotagmin 1 also known as p65, is an integral membrane glycoprotein of neuronal synaptic vesicles and secretory granules of neuroendocrine cells that is widely (but not ubiquitously) expressed in the central and peripheral nervous system. It has a variable N-terminal domain that is exposed to the lumen of the vesicle and a conserved cytoplasmic tail that contains two Ca2+-binding C2-domains.
Ca2+-binding to synaptotagmin triggers exocytosis of synaptic vesicles, thus linking Ca2+-influx during depolarization to neurotransmitter release.
Lumenal antibodies were used in living neurons to label synaptic vesicles from the outside via endocytotic uptake.
