Product Overview
This rabbit polyclonal antibody targets syntaxin-1A (gene STX1A) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 33.0 kDa, and the supplier reports an observed band at about 37 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.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|
Samples with a confirmed band (WB): rat brain tissue, mouse brain tissue, U87 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE, 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.
Immunogen
Synthetic peptide from the N-terminal region of human syntaxin 1a. It differs from the mouse and rat sequences at one residue.
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.
