Anti-STX3 Antibody

A rabbit polyclonal primary antibody from Antibodies.com targets Syntaxin 3 (STX3), a plasma membrane t-SNARE protein that mediates vesicle fusion and exocytosis in neuronal and epithelial cells. Raised in rabbit hosts and supplied as an unconjugated IgG, this reagent is validated for Western blot applications and shows reactivity with human, mouse, and rat samples, supporting cross-species studies of SNARE-dependent membrane trafficking.

Each vial contains 200 µl of polyclonal antiserum, suitable for multiple blotting experiments. Syntaxin 3 is widely studied in the context of synaptic vesicle docking, apical protein delivery in polarized epithelial monolayers, and SNARE complex assembly with partners such as SNAP-25 and synaptobrevin. Researchers investigating epithelial polarity, neurotransmitter release, or related vesicle trafficking mechanisms can apply this primary antibody to detect endogenous STX3 in tissue lysates and cell line extracts.

The unconjugated format allows flexible selection of secondary antibody and detection chemistry, supporting chemiluminescent or fluorescent Western blot workflows depending on laboratory preference. Store refrigerated and avoid repeated freeze-thaw cycles to preserve antibody activity across experiments.
