Product Overview
Clone 21S16 is a rabbit monoclonal antibody that recognizes syntaxin-4 (gene STX4) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 34.2 kDa, and the supplier reports an observed band at about 34 kDa.
Syntaxin-4 (STX4) is a plasma membrane SNARE that mediates docking and fusion of transport vesicles. In adipocytes and muscle it is needed for insulin-stimulated movement of the glucose transporter GLUT4 to the cell surface, and it also contributes to insulin secretion and to delivery of the dopamine transporter in neurons.

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).
