Precision

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.

Linearity

To assess the linearity of the assay, samples were spiked with high concentrations of human EDN2 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 %	103
	Range %	96-107
1:2	Average %	86
	Range %	81-92
1:4	Average %	94
	Range %	87-98
1:8	Average %	86
	Range %	80-91

Recovery

The recovery of human EDN2 spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	93	87-98
EDTA plasma (n=4)	94	90-98

Target Background

Function
(From Uniprot)

Endothelins are endothelium-derived vasoconstrictor peptides.

Gene References into Functions

EDN2 expression in left internal mammary arteries depends on tissue harvesting technique. PMID: 24647318
Overexpression of Edn2 in the mouse retina causes an excess of tip cells and inhibits vascular growth. Overexpression of Edn2 in the brain and skin had no effect, but vascular development was inhibited in midgestation mouse embryos. PMID: 24043815
Endothelin 2 and endothelin receptor type B may be a regenerative pathway for central nervous system myelination and remyelination. PMID: 23518706
Studies revealed hypermethylation of EDN2 and EDN3 genes in human primary colon cancers and in a panel of human colon cancer cell lines. Epigenetic inactivation of ET-2 and ET-3 occurs frequently in both rat and human colon cancers. PMID: 22865632
plasma levels of big ET-2, and big ET-3 are markedly increased in patients with end stage renal disease on hemodialysis PMID: 22921304
In granulosa lutein cells from women with polycystic ovary syndrome, endothelin-2 mRNA was reduced as compared with normally ovulating women PMID: 22727793
although endothelin 2 does not appear to be an independent prognostic marker, there is evidence of a putative role in clear cell renal cell carcinoma progression PMID: 22047647
Endothelin-2 is a macrophage chemoattractant. ET-2 expression by tumors may modulate the behavior of macrophages such that activated cells accumulate in areas of hypoxia. PMID: 12207323
Endothelin-2 is a hypoxia-induced autocrine survival factor for breast tumor cells PMID: 12516960
The EDN2 A985 allele, which is considered to be protective in cardiovascular disease, may be a risk factor for atrial fibrillation in patients with hypertrophic cardiomyopathy. PMID: 18037749
