Cat. No. 105 311AF 100 µg purified IgG, lyophilized, fluorescence-labeled with AcidiFluor Orange 

AcidiFluor Orange® is a pH-sensitive dye, fluorescent only after antibody internalization at the acidic pH of the lumen of the cellular compartment e.g. the synaptic vesicle.
AcidiFluor Orange can be detected with the filter sets for Cy3.

. Albumin was added for stabilization. For reconstitution add 100 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.

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.
