ZO-1 Antibody — Published figure using ZO-1 monoclonal antibody (Product # 339194)

ZO-1 Antibody in Immunofluorescence (IF) — Immunofluorescence analysis of ZO-1/TJP1 Antibody, Alexa Fluor® 594 conjugate (ZO1-1A12) was done on 90% confluent log phase CaCo2 cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with ZO-1/TJP1 Antibody, Alexa Fluor® 594 conjugate (ZO1-1A12) (Product # 339194) at 1µg/mL in 1% BSA and incubated for 3 hours at room temperature (Panel a: red). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). Panel c: red). Panel c is a merged image showing cell junctional localization. Panel d is a no primary antibody control. The images were captured at 40X magnification.

Target Information

ZO-1 forms complexes with either ZO-2 or ZO-3. In addition, these proteins can also associate with claudin, occludin and F-actin, at tight junction stands, where they provide a linkage between the actin cytoskeleton and the tight junction. ZO-1 expression is significantly reduced in many breast cancer lines. ZO-2 and ZO-3 are ubiquitously expressed within epithelial tight junctions, and unlike ZO-1, which is also expressed at cell junctions of cardiac myocytes, ZO-2 is not expressed in nonepithelial tissue. ZO-1 is a protein located on a cytoplasmic membrane surface of intercellular tight junctions. ZO-1 may be involved in signal transduction at cell-cell junctions. Two transcript variants encoding distinct isoforms have been identified for the ZO-1 gene. Diseases associated with ZO-1 dysfunction include Celiac Disease and Congenital Nephrotic Syndrome.
