TJP1 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level TJP1 were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level TJP1 were tested on 3 different plates, 8 replicates in each plate. Intra-Assay: CV Inter-Assay: CV Inter-Assay: CV Inter-Assay: CV

Tight junction protein 1; tight junction protein ZO-1; ZO-1; zona occludens 1; Zona occludens protein 1; zonula occludens 1 protein; Zonula occludens protein 1.

TJP1, TJP2, and TJP3 are closely related scaffolding proteins that link tight junction (TJ) transmembrane proteins such as claudins, junctional adhesion molecules, and occludin to the actin cytoskeleton (PubMed:7798316, PubMed:9792688) . The tight junction acts to limit movement of substances through the paracellular space and as a boundary between the compositionally distinct apical and basolateral plasma membrane domains of epithelial and endothelial cells. Necessary for lumenogenesis, and particularly efficient epithelial polarization and barrier formation (By similarity) . Plays a role in the regulation of cell migration by targeting CDC42BPB to the leading edge of migrating cells (PubMed:21240187) . Plays an important role in podosome formation and associated function, thus regulating cell adhesion and matrix remodeling (PubMed:20930113) . With TJP2 and TJP3, participates to the junctional retention and stability of the transcription factor DBPA, but is not involved in its shuttling to the nucleus (By similarity) .

Aviva Systems Biology TJP1 ELISA Kit (Human) (OKDD00562) is based on standard sandwich enzyme-linked immuno-sorbent assay methodology. An antibody for TJP1 has been pre-coated onto a 96-wellplate (12 x 8 Well Strips) . Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for TJP1 is added, incubated and removed. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm and is quantitatively proportional to the amount of sample TJP1 captured in well.
