Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
To assess the linearity of the assay, samples were spiked with high concentrations of human AGR3 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
  Sample Serum(n=4)  
1:1 Average % 85

Target Data

Function Required for calcium-mediated regulation of ciliary beat frequency and mucociliary clearance in the airway. Might be involved in the regulation of intracellular calcium in tracheal epithelial cells.
Gene References into Functions
  1. Results show that AGR3 was highly upregulated in low-grade serous carcinoma (LGSC) compared to high-grade serous carcinoma (HGSC). It can be use along with p53 for differential diagnosis of HGSC and LGSC. PMID: 29620196
  2. transcriptionally activated in hepatitis C virus-infected cells by HCV NS5A PMID: 25868611
  3. Data show the potential usability of anterior gradient homolog 3 (AGR3) and anterior gradient homolog 2 (AGR2) as biomarkers for blood-based early detection of breast cancer. PMID: 25875093
  4. AGR3 is a specialized member of the PDI family that plays an unexpected role in the regulation of CBF and mucociliary clearance in the airway. PMID: 25751668
  5. Relying on available data and in silico analyses, study shows that AGR2 and AGR3 proteins are co-expressed or uncoupled in context-dependent manners in diverse carcinomas and healthy tissues. PMID: 25666661
  6. AGR3 was is predominantly expressed in liver cholangiocytes but not present in liver hepatocytes, making this protain a good marker for differential diagnosis of intrahepatic cholangiocarcinoma PMID: 24747240
  7. AGR3 expression in ovarian cancer is independent of oestrogen-receptor expression. PMID: 22361111
  8. AGR3 could serve as a prognostic marker for survival in patients with low grade and high grade serous ovarian carcinomas. PMID: 21451362
  9. hAG-2 and hAG-3, human homologues of genes involved in differentiation, are associated with oestrogen receptor-positive breast tumours and interact with metastasis gene C4.4a and dystroglycan [hAG-3 protein] PMID: 12592373
  10. specific induction of Hag2 and Hag3 during hormone-induced breast carcinomas further support developmental specificity for the PDI/ERp family members PMID: 15935701
