Product Overview
Clone BIE-19 is a rabbit monoclonal antibody that recognizes synaptophysin (gene SYP) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. 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, mouse brain 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 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human colon tissue, human pancreas tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): PC-12 cells.
Immunogen
Synthetic peptide based on the sequence of human synaptophysin.
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.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
