線性度：

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

回收率：

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

最新研究進展：

ORM2，全稱為酸性糖蛋白，是一種血漿蛋白。最近的研究表明，ORM2在多種疾病中發揮著重要作用，包括炎癥、心血管疾病和肝病等。ORM2參與了細胞凋亡、免疫反應和糖代謝等生物學過程。
功能：

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.

Particularly, the interaction between non-neuronal cells plays a central role in regulating brain inflammation, which is closely linked to many brain disorders.
