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 pantetheinase in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

(From Uniprot)
Amidohydrolase that hydrolyzes specifically one of the carboamide linkages in D-pantetheine thus recycling pantothenic acid (vitamin B5) and releasing cysteamine.
Gene References into Functions
  1. findings suggest that the metabolic pathway catalyzed by VNN1 pantetheinase plays a suppressive role in IAV infection in the respiratory tract, especially in severe conditions under hypercytokinemia PMID: 28576495
  2. Data show that G protein-coupled receptor, family C, group 5, member A protein (GPRC5A) regulates oxidative stress through vanin 1 protein (VNN1). PMID: 28316092
  3. These data suggest that urinary vanin-1 is an early predictive biomarker for decline in eGFR in patients with urothelial carcinoma after dosing of cisplatin PMID: 27317936
  4. serum pantetheinas, encoded by the VNN1 gene, level regulates erythrocyte life span and modulates the risk of developing complicated malaria. PMID: 26343328
  5. VNN1 contributes to corticosteroid responsiveness, and changes in VNN1 nasal epithelial mRNA expression and VNN1 promoter methylation might be clinically useful biomarkers of treatment response in asthmatic children. PMID: 25910714
  6. Our study provides strong biological evidence for the association of the identified SNP with BP and suggests that vanin-1 misfolding and degradation are the underlying molecular mechanism. PMID: 25233454
  7. show that hepatic vanin-1 is under extremely sensitive regulation by PPARalpha and that plasma vanin activity could serve as a readout of changes in PPARalpha activity in human subjects PMID: 24751833
  8. The X-ray crystal structure of human vanin 1 at 2.25 A resolution is presented, which is the first reported structure from the vanin family, as well as a crystal structure of vanin 1 bound to a specific inhibitor. PMID: 25478849
  9. Serum vanin-1 levels may be low in the end-stage renal failure and transiently increase after transplant owing to transient renal function deterioration, which does not lead to elevation of serum creatinine levels in renal transplant patients. PMID: 24702142
  10. Our results suggest that vanin-1 can distinguish between chronic responders and non-responders ITP patients as well as between newly diagnosed ITP patients and healthy controls. PMID: 23534352

  15. Liver contributes to Vanin-1 secretion in serum and PPARalpha is a limiting factor in serum Vnn1 production. PMID: 24140347
  16. data do not support a major role for the Vanin 1 T26I variant in determining blood pressure level and incident ischemic events PMID: 21550219

  20. Overexpression of VNN1, an oxidative stress sensor in epithelial cells, was most strongly associated with progression to chronic immune thrombocytopenia PMID: 21325602
  21. The combination of VNN1 and MMP9 may be used as a novel blood biomarker panel for the discrimination of pancreatic cancer-associated diabetes from type 2 diabetes. PMID: 20571492
  22. Pantetheinase (Vnn1) is critical for the host susceptibility to malaria. PMID: 17312006
  23. missense SNP rs2272996 (or N131S) in the VNN1 gene was significantly associated with hypertension in African Americans and the association was replicated in Mexican Americans; a non-significant opposite association was observed in European Americans PMID: 18043751
  24. vanin-1 and vanin-3 are induced at the mRNA and protein level by psoriasis-associated proinflammatory cytokines (Th17/Th1) but not by Th2 cytokines. PMID: 19322213
