Product Overview
This rabbit polyclonal antibody targets synaptophysin (gene SYP) in human, mouse and rat samples and is validated for Western blot, IHC and ICC/IF. The predicted molecular weight is 33.8 kDa, and the supplier reports an observed band at about 38 kDa.
Synaptophysin (SYP) is an abundant integral membrane glycoprotein of synaptic vesicles in neurons and neuroendocrine cells. It interacts with synaptobrevin and is involved in vesicle organization and synaptic plasticity, and it is one of the most widely used markers for synapses and neuroendocrine tissue.

Samples with a confirmed band (WB): rat brain tissue, rat hippocampus tissue, mouse brain tissue, mouse hippocampus tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.

Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): SH-SY5Y cells.
Samples with confirmed staining (ICC/IF): mouse pancreas tissue, rat pancreas tissue, mouse brain tissue.
Immunogen
Synthetic peptide from the N-terminal region of human synaptophysin/SYP. Sequence identity with the mouse and rat orthologs: 91.3%.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places synaptophysin in the synapse. Tissue expression noted by UniProt (human): Expressed in the brain, with expression in the hippocampus, the neuropil in the dentate gyrus, where expression is higher in the outer half of the molecular layer than in the inner half, and in the neuropil of CA4 and CA3. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
