Anti-ZO1 tight junction protein antibody (ab59720)抗ZO1紧密连接蛋白抗体产品信息：

• Product name：Anti-ZO1 tight junction protein antibodySee all ZO1 tight junction protein primary antibodies ...
• Description

  Rabbit polyclonal to ZO1 tight junction protein

• Specificityab59720 recognises both ZO1 tight junction alpha-minus and alpha-plus isoforms. The protein is abundant in endothelial cells and the highly specialized epithelial junctions. Although we have an image for IHC-Fr, customers report variable results in this application. If you would like to use in IHC-Fr then we suggest using ethanol instead of acetone. Although we have references for IHC-P, customers report variable results in this application. IHC-Fr and IHC-P are therefore not covered by our Abpromise guarantee.
• Tested applicationsICC/IF, Flow Cyt, IHC (PFA fixed), WB, IHC-P more details

Applications

Our Abpromise guarantee covers the use of ab59720 in the following tested applications.

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

Target

• FunctionThe N-terminal may be involved in transducing a signal required for tight junction assembly, while the C-terminal may have specific properties of tight junctions. The alpha domain might be involved in stabilizing junctions.
• Tissue specificityThe alpha-containing isoform is found in most epithelial cell junctions. The short isoform is found both in endothelial cells and the highly specialized epithelial junctions of renal glomeruli and Sertoli cells of the seminiferous tubules.
• Sequence similaritiesBelongs to the MAGUK family.
  Contains 1 guanylate kinase-like domain.
  Contains 3 PDZ (DHR) domains.
  Contains 1 SH3 domain.
  Contains 1 ZU5 domain.
• DomainThe second PDZ domain mediates interaction with GJA12.
• Post-translational
  modificationsPhosphorylated. Dephosphorylated by PTPRJ.
• Cellular localizationCell membrane. Cell junction > tight junction. Movement of ZO-1 from the cytoplasm to membrane is an early event occurring concurrently with cell-cell contact.

• Immunocytochemistry/ Immunofluorescence - Anti-ZO1 tight junction protein antibody (ab59720)

  ab59720 staining ZO1 in Caco-2 cells treated with (±)-palmitoylcarnitine chloride (ab141122), by ICC/IF. Membranar ZO1 expression loss correlates with increased concentration of (±)-palmitoylcarnitine chloride, as described in literature.
  The cells were incubated at 37°C for 1 hour in media containing different concentrations of ab141122 ((±)-palmitoylcarnitine chloride) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab59720 (0.5 μg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

  ICC/IF image of ab59720 stained MCF-7 cells. The cells were 4% formaldehyde fixed (10 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 (ab59720, 1µg/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.

  Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 1% BSA for 30 minutes at 25°C. Samples were incubated with primary antibody (1/200 in diluent) for 16 hours at 4°C. An AlexaFluor®488-conjugated goat anti-rabbit polyclonal IgG (1/500) was used as the secondary antibody.
