Our Abpromise guarantee covers the use of ab12369 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
WB Use a concentration of 4 µg/ml. Detects a band of approximately 35 kDa (predicted molecular weight: 33.3 kDa). human and 1/1000-1/2000 for other species.
IP Use a concentration of 10 µg/ml.
ICC Use at an assay dependent dilution.


  • Function
    Essential for epithelial morphogenesis. May mediate Ca(2+)-regulation of exocytosis acrosomal reaction in sperm.
  • Sequence similarities
    Belongs to the syntaxin family.
    Contains 1 t-SNARE coiled-coil homology domain.
  • Cellular localization
  • Information by UniProt
  • Database links
  • Form
    Inhibition of syntaxin-2 and Vamp8 function by overexpression of nonmembrane-anchored mutants caused failure of cytokinesis leading to the formation of binucleated cells. There are 3 isoforms produced by alternative splicing.

  • ICC/IF image of ab12369 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab12369, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
