Precision

Linearity

To assess the linearity of the assay, samples were spiked with high concentrations of human ORM2 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)
1:100	Average %	98
	Range %	90-102
1:200	Average %	89
	Range %	83-94
1:400	Average %	101
	Range %	93-105
1:800	Average %	105
	Range %	97-110

Recovery

The recovery of human ORM2 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	82-95
EDTA plasma (n=4)	94	90-98

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.

Function(From Uniprot)

Functions as transport protein in the blood stream. Binds various hydrophobic ligands in the interior of its beta-barrel domain. Also binds synthetic drugs and influences their distribution and availability. Appears to function in modulating the activity of the immune system during the acute-phase reaction.
