Cat. No. 105 308Ab635P 50 µg purified recombinant IgG, lyophilized, fluorescence-labeled with abberior STAR635P.

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.

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.

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.
