Precision

Linearity

To assess the linearity of the assay, samples were spiked with high concentrations of human GPC4 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 %	96
	Range %	92-104
1:2	Average %	92
	Range %	88-96
1:4	Average %	87
	Range %	81-94
1:8	Average %	98
	Range %	92-106

Recovery

The recovery of human GPC4 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)	90	85-96
EDTA plasma (n=4)	95	91-99

Target Background

Function (From Uniprot)	Cell surface proteoglycan that bears heparan sulfate. May be involved in the development of kidney tubules and of the central nervous system.
Gene References into Functions	The T allele of GPC4 may represent a risk factor for Epstein-Barr virus-associated gastric carcinoma. PMID: 27071854 According to behavioral studies, downregulation of Gpc4 by Gpc4 siRNA decreased spontaneous seizure frequency, while upregulation of Gpc4 by recombinant Gpc4 overexpression led to a converse result. These findings support the hypothesis that increased expression of Gpc4 in the brain is associated with epileptic seizures. PMID: 27425250 serum level elevated in polycystic ovary syndrome and correlated with fat distribution and cardiovascular risk PMID: 26486309 Data suggest gender difference in circulating GPC4 levels in nonalcoholic fatty liver disease; GPC4 levels in women appear to correlate with cardiometabolic risk factors (adiposity/body fat distribution, insulin resistance, and arterial stiffness). PMID: 23633195 new function of miR-125a by targeting gene glypican-4 in cell growth process PMID: 22644326 Findings establish that Gpc4 acts at the interface of extrinsic and intrinsic signal regulation to fine tune stem cell fate.
