Synaptotagmin1 antibody luminal domain - 105 103AF

Synaptotagmin1 is a Ca2+-sensor on synaptic vesicles that triggers neurotransmitter release

pH-sensitive probe fluorescent only under acidic conditions

Rabbit polyclonal purified antibody
Cat. No.: 105 103AF
Amount: 50 µg
Price: $485.00
Cat. No. 105 103AF 50 µg specific antibody, lyophilized. Affinity purified with the immunogen, 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.
It can be detected with established fluorescence detection systems.

AcidiFluor Orange: λex 570 nm / λem 590 nm

 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.
