  IF Staining of U2OS using CL488-82870

  Immunofluorescent analysis of (4% PFA) fixed U2OS cells using CoraLite® Plus 488 ZO-1 antibody (CL488-82870, Clone: 2P13 ) at dilution of 1:600.

• 

  FC experiment of MCF-7 using CL488-82870

  1x10^6 MCF-7 cells were intracellularly stained with 0.4 ug CoraLite® Plus 488-conjugated ZO-1 Recombinant antibody (CL488-82870, Clone:2P13)(red), or 0.4 ug CoraLite® Plus 488-conjugated Rabbit IgG control Rabbit PolyAb (CL488-30000) (blue). Cells were fixed with 4% PFA and permeabilized with Flow Cytometry Perm Buffer (PF00011-C).

Tested Applications

• Positive IF/ICC detected in: U2OS cells
• Positive FC (Intra) detected in: MCF-7 cells

Recommended dilution

• Immunofluorescence (IF)/ICC: IF/ICC : 1:300-1:1200
• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.40 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

Tight junction (or zonula occludens) form the continuous intercellular barrier between epithelial and endothelial cells, which is required to separate tissue spaces and regulate selective movement of solutes across the epithelium and endothelium (PMID: 20066090). ZO-1 (also known as TJP1) is a peripheral membrane phosphoprotein located on the cytoplasmic face and is expressed in tight junctions of both epithelial and endothelial cells (PMID: 3528172). It binds the transmembrane proteins occludin and the claudins linking them to cytoskeletal actin (PMID: 17418867). ZO-1 belongs to a family of multidomain proteins known as the membrane-associated guanylate kinase homologs (MAGUKs). It is a pivotal tight junction protein and may be involved in signaling mechanisms regulating cell proliferation and differentiation (PMID: 22782886).
