Description

Rat Monoclonal Antibody

The monoclonal antibody R26.4C recognizes the tight junction protein 1, ZO-1 (zona occludens) of rat, mouse, canine, and porcine. ZO-1 is a member of the MAGUK family of tight junction associated scaffolding proteins, each containing a PDZ, SH3 and guanylate kinase-like (GUK) domain. ZO-1 is an integral member of the tight junction complex which forms a barrier to paracellular movement of substances, separating apical and basolateral fluids in relation to the epithelial cell layer. ZO-1 forms complexes with family members ZO-2, ZO-3, as well as occludin, cingulin, claudin-1-8, actin, alpha-catenin, the Ras-effector molecule AF-6, ZONAB, Apg-2, and the junctional adhesion molecules (JAM)-A-C. ZO-1 is thought to anchor the actin cytoskeleton to the tight junction. ZO-1 and ZO-2 have been shown to regulate cell cycle and proliferation with recent evidence highlighting the down-regulation of ZO-1 and ZO-2 with cancer progression. Applications Reported: This R26.4C antibody has been reported for use in immunohistochemical staining of frozen tissue sections, microscopy, and immunocytochemistry. Applications Tested: This R26.4C antibody has been tested by immunocytochemistry of formaldehyde-fixed and permeablized cells and can be used at less than or equal to 1 μg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Filter Recommendation: When using this eFluor 570 antibody conjugate, we recommend a f...

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.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

What buffers are compatible with the eFluor Organic fluorochromes and eVolve QDots?

The eFluor Organic fluorochromes and eVolve QDots can be used with flow staining buffers containing PBS and protein.

What is the difference between eFluor Organic Dyes and eVolve Qdots?

The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
