Cat. No. 105 308Ab635P	50 µg purified recombinant IgG, lyophilized, fluorescence-labeled with abberior STAR 635P. abberior STAR^® dyes have been especially developed for for Stimulated Emission Depletion (STED) microscopy which allows higher resolution imaging compared to confocal laser scanning microscopy. For many of the fluorescence labeled antibodies conjugated to abberior STAR^® dyes established fluorescence detection systems can be used. abberior STAR^® 635P: λ_ex 638 nm / λ_em 651 nm abberior STAR^® ORANGE: λ_ex 589 nm / λ_em 616 nm abberior STAR^® RED: λ_ex 638 nm / λ_em 655 nm This product or portions thereof is manufactured under license from abberior GmbH. abberior STAR is a trademark of abberior GmbH, Goettingen/Germany. Purchase of reagents related to the abberior STAR technology from Synaptic Systems GmbH provides a license for non-profit and in-house research use only. Any application of above mentioned technology for commercial purpose requires a separate license from abberior GmbH. 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

Synaptotagmin1, 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.
