ZO-1 Antibody (339188) in ICC/IF

Immunofluorescence analysis of ZO-1 was performed using 90% confluent log phase Caco-2 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with ZO-1 Monoclonal Antibody (ZO1-1A12), Alexa Fluor 488 at 5µg/mL in 0.1% BSA and incubated for 3 hours at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin ... View More

ZO-1 Antibody — Figure 7 Induction of EMT after CPT treatment of SKOV3 cells A. RT-qPCR expression analysis of the indicated EMT marker genes after the indicated times of CPT treatment (sample size: n >= 3). B. Flow cytometry analysis of intracellular SMA after 0, 2 or 21 weeks of CPT treatment (sample size: n = 3). Values represent the fold change (FC) in the number of positive cells relative to small cells on day 0 (normalized to 1). Cells gated for small cells (forward and sideward scatter as untreated SKOV3 cells) and larger cells (forward and sideward scatter larger than for SKOV3 cells). C. Flow cytometry analysis of IL-1beta expression in SMA-expressing SKOV3-R cells gated as in panel B. D. Labeling of actin filaments with California Red-conjugated phalloidin (red) after different periods of CPT exposure. E. Additional staining of the tight junction (zonula occludens) protein constituent ZO-1 by indirect immunofluorescence (green) in untreated SKOV3 and SKOV3-R cells. Nuclei were stained with DAPI in panels D and E. F. RT-qPCR analysis of VIM expression in SKOV3-R cells (21w) and the same cells grown in the absence of CPT for 7 days. G. Pro-inflammatory and EMT marker gene expression after cyclic CPT treatment (1 day CPT, 21 days recovery, 4 cycles) compared to untreated cells (sample size: n = 3). {TM}

Product Specific Information

This monoclonal antibody detects ZO-1alpha+ and ZO-1alpha- isoforms. The antibody is specific for ZO-1 proteins; cross-reactivity with the related ZO-2 protein has not been observed. Species reactivity includes human (Caco-2 Cell line) and dog (MDCK cell line). Based on sequence homology, reactivity with other species is likely but has not been confirmed.

For Alexa Fluor 488 excitation 495 nm/emission 519 nm. Each lot of this antibody is tested for specificity by immunofluorescence. Expires one year from date of receipt when stored as instructed.

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.
