ZO-1 Antibody (740002M) in WB
Comparison of western blot performance was done using ZO-1 Recombinant Mouse Monoclonal Antibody (ZO1-1A12) (Product # 740002M) and top-cited ZO-1 antibody. ZO-1 expression was detected at ~200 kDa in Fig. (a). Caco-2 whole cell extracts loaded at varied concentrations 30 µg (Lane 1), 20 µg (Lane 2), 10 µg (Lane 3) and 5 µg (Lane 4) were electrophoresed using NuPAGE™ 3 to 8%, Tris-Acetate, 1.0 mm, Mini Protein Gel (Product # EC6695BOX), 10-well. Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB33001) by i... View More

Product Specific Information
Recombinant mouse monoclonal antibodies are produced using in vitro expression systems. Recombinant antibodies are produced using specific genes that code for the desired antibodies. These genes are cloned into an expression vector and expressed in vitro. The advantages of recombinant antibodies include better specificity and lot-to-lot consistency.
It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
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.
