Product Overview
Clone 25S37 is a rabbit monoclonal antibody that recognizes syntaxin-1A (gene STX1A) in human, mouse and rat samples and is validated for Western blot, immunoprecipitation and flow cytometry. The predicted molecular weight is 33.0 kDa, and the supplier reports an observed band at about 33 kDa.
Syntaxin-1A (STX1A) is a plasma membrane SNARE that forms the core fusion complex with SNAP25 and the vesicle SNARE VAMP2. Zippering of these SNAREs brings synaptic vesicles and the presynaptic membrane together for calcium-triggered neurotransmitter release, and STX1A also supports hormone secretion from endocrine cells.

Immunogen
Synthetic peptide based on the sequence of human STX1A.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places syntaxin-1A in the synapse and cell membrane. Tissue expression noted by UniProt (human): Highly expressed in embryonic spinal cord and ganglia and in adult cerebellum and cerebral cortex... 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).
