Overview
Anti-Syntaxin 1 Antibody is an antibody targeting STX1A, Synaptotagmin-associated 35 kDa protein, P35A, P35-1, Neuron-specific antigen HPC-1 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IF, IHC, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: STX1A, Synaptotagmin-associated 35 kDa protein, P35A, P35-1, Neuron-specific antigen HPC-1 (also reported as STX1A, Synaptotagmin-associated 35 kDa protein, P35A, P35-1, Neuron-specific antigen HPC-1).
- Immunogen/epitope region: Intracellular, N-terminus.
- Homology note: Human, mouse- 264/265 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Rat, Mouse.
- Cited use: IP (literature use does not guarantee performance in every setup).
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by DNA sequence and SDS-PAGE.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
Syntaxin 1 is a member of the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) protein superfamily. The family includes 36 members in humans and is characterized by the SNARE motif, an evolutionarily conserved stretch of 60-70 amino acids that are arranged in heptad repeats1,2.SNARE proteins are involved in exocytosis and intracellular vesicle trafficking and are essential for cell growth, hormone secretion and neurotransmission, processes that require rapid, targeted, and regulated membrane fusion1,2.SNAREs can be roughly divided into vesicular (v-SNAREs) and target (t-SNAREs) based on their distribution on the transport vesicle or target membrane respectively. Thus, assembly of cognate v-/t-SNAREs between two opposing membranes generates trans-SNARE complexes, which bring the lipid bilayers in close proximity and drive membrane fusion.Syntaxin 1, like most SNAREs, is a type IV membrane protein with a relatively large N-terminus containing the SNARE motif located in the cytoplasmic side and a transmembrane domain located close to the C-terminus that functions as an anchor1,2.Syntaxin 1 has been extensively studied for its role on neuronal and neuroendocrine cell exocytosis where it functions as the plasma membrane protein t-SNARE, which together with the vesicular v-SNARE protein VAMP and the membrane-associated SNAP-25 (synaptosome-associated protein 25 kDa), forms a trimeric, four-helical complex, which drives fusion of the two opposing bilayers1,2.Syntaxin 1 together with SNAP-25 is the target of the neurotoxin botulinum neurotoxin type C (BoNT/C) which following proteolytic degradation of the proteins causes inhibition of neurotransmitter release 3.
Research relevance and current trends
- Mapping receptor/channel localization across neuronal subtypes and subcellular compartments.
- Linking trafficking or surface expression changes to activity-dependent signaling and plasticity.
- Using KO/KD or blocking-peptide concepts to strengthen antibody-based target assignment.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-NR002.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
