Anti-Synapsin I (phospho-S9) Antibody

Phospho-specific detection of Synapsin I at serine 9 is supported by this rabbit polyclonal reagent from Antibodies.com, an unconjugated primary antibody targeting a key regulatory site on the presynaptic vesicle-associated protein. The antibody is supplied at 1 mg/ml in phosphate buffered saline (PBS) containing 15 mM sodium azide at approximately pH 7.2, and is validated for Western blot, immunohistochemistry, and immunofluorescence workflows. Confirmed reactivity spans human, mouse, and rat samples, supporting translational neuroscience research into neurotransmitter release and short-term synaptic plasticity. The 100 µl format supports multiple experiments, while the polyclonal host response provides broader epitope coverage around the phospho-S9 site than a typical monoclonal reagent. Aliquot upon arrival and store refrigerated while protecting from light to maintain phospho-specific binding activity.
