Product Overview
Clone 23S96 is a rabbit monoclonal antibody that recognizes syntaxin-binding protein 1 (gene STXBP1) in human, mouse and rat samples and is validated for Western blot, IHC and ICC/IF. The predicted molecular weight is 67.6 kDa, and the supplier reports an observed band at about 65 kDa.
Munc18-1 (STXBP1) is a Sec1/Munc18-family protein that binds syntaxin-1 and templates assembly of the neuronal SNARE complex. It is essential for synaptic vesicle docking and neurotransmitter release, and STXBP1 mutations cause a severe early-onset epileptic encephalopathy.

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).
