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

アプリケーション Abreviews 特記事項
Flow Cyt Use 1µg for 106 cells. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
WB Use a concentration of 0.1 - 1 µg/ml. Detects a band of approximately 240 kDa (predicted molecular weight: 195 kDa).

Abcam recommends using BSA as the blocking agent.

IP Use a concentration of 5 µg/ml.

ターゲット情報

  • 機能The 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.
  • 組織特異性The 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.
  • 配列類似性Belongs to the MAGUK family.
    Contains 1 guanylate kinase-like domain.
    Contains 3 PDZ (DHR) domains.
    Contains 1 SH3 domain.
    Contains 1 ZU5 domain.
  • ドメインThe second PDZ domain mediates interaction with GJA12.
  • 翻訳後修飾Phosphorylated. Dephosphorylated by PTPRJ.
  • 細胞内局在Cell membrane. Cell junction > tight junction. Movement of ZO-1 from the cytoplasm to membrane is an early event occurring concurrently with cell-cell contact.

Anti-ZO1 tight junction protein antibody [mAbcam 61357] 画像

  • ZO1 tight junction protein was immunoprecipitated using 0.5mg Hek293 whole cell extract, 5µg of Mouse monoclonal to and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Hek293 whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab61357.

    Secondary: Goat polyclonal to mouse IgG light chain specific (HRP) at 1/20,000 dilution.

    Band: 240kDa, non specific band - 90kDa: We are unsure as to the identity of this extra band; ZO1 tight junction protein

  • All lanes : Anti-ZO1 tight junction protein antibody [mAbcam 61357] (ab61357) at 5 µg/ml

    Lane 1 : HepG2 (Human hepatocellular liver carcinoma cell line) Whole Cell Lysate
    Lane 2 : HEK293 (Human embryonic kidney cell line) Whole Cell Lysate
    Lane 3 : A431 (Human epithelial carcinoma cell line) Whole Cell Lysate
    Lane 4 : Caco 2 (Human colonic carcinoma cell line) Whole Cell Lysate

    Lysates/proteins at 20 µg per lane.

    Secondary
    Goat polyclonal to Mouse IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 195 kDa
    Observed band size : 240 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 38 kDa,44 kDa,48 kDa,85 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 30 seconds
    The 240-kDa band observed is comparable to the molecular weight seen with other commercially available antibodies to ZO1 tight junction protein.
  • Overlay histogram showing MCF-7 cells stained with ab61357 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab61357, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

The MCF7 FACS data we show on the datasheet came from cells that were harvested with trypsin, not from cells that were scraped from the culture dishes. If you are concerned that trypsin will remove ZO1 from your cells, I recommend comparing FACS data f...
