The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 55 kDa (predicted molecular weight: 55 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
May play a role in neurotransmitter secretion.
Expressed abundantly in pancreas, heart and brain with low levels of expression in lung, kidney, liver and thyroid.
Contains 1 AH domain.
Cytoplasm > cytosol. Golgi apparatus membrane. Cytoplasmic vesicle > secretory vesicle membrane. Cytoplasmic vesicle > secretory vesicle > synaptic vesicle membrane. Predominantly cytosolic. Also exists as a membrane-bound form which has been found associated with synaptic vesicles and also with the Golgi complex and immature secretory granules.
