Datasheets/ManualsPrintable datasheet for ERN1 ELISA Kit (Human) (OKCD08139)
Product Info
Predicted Species ReactivityHomo sapiens|Human
ApplicationEnzyme-linked Immunosorbent assay-Sandwich
ELISA Kit Detection MethodColorimetric
ELISA Kit Duration3h
ELISA Kit PrincipleThe test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Endoplasmic Reticulum To Nucleus Signalling 1 (ERN1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Endoplasmic Reticulum To Nucleus Signalling 1 (ERN1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Endoplasmic Reticulum To Nucleus Signalling 1 (ERN1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Endoplasmic Reticulum To Nucleus Signalling 1 (ERN1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
ELISA Kit Range0.156-10ng/mL
ELISA Kit ReproducibilityIntra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Endoplasmic Reticulum To Nucleus Signalling 1 (ERN1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Endoplasmic Reticulum To Nucleus Signalling 1 (ERN1) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Protein NameSerine/threonine-protein kinase/endoribonuclease IRE1
Description of TargetSerine/threonine-protein kinase and endoribonuclease that acts as a key sensor for the endoplasmic reticulum unfolded protein response (UPR) (PubMed:11779464, PubMed:11175748, PubMed:12637535, PubMed:9637683, PubMed:21317875). In unstressed cells, the endoplasmic reticulum luminal domain is maintained in its inactive monomeric state by binding to the endoplasmic reticulum chaperone HSPA5/BiP (PubMed:21317875). Accumulation of misfolded protein in the endoplasmic reticulum causes release of HSPA5/BiP, allowing the luminal domain to homodimerize, promoting autophosphorylation of the kinase domain and subsequent activation of the endoribonuclease activity (PubMed:21317875). The endoribonuclease activity is specific for XBP1 mRNA and excises 26 nucleotides from XBP1 mRNA (PubMed:11779464, PubMed:24508390, PubMed:21317875). The resulting spliced transcript of XBP1 encodes a transcriptional activator protein that up-regulates expression of UPR target genes (PubMed:11779464, PubMed:24508390, PubMed:21317875).
