Precision

Linearity

To assess the linearity of the assay, samples were spiked with high concentrations of human PLA2 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)
1:5	Average %	93
	Range %	88-97
1:10	Average %	104
	Range %	100-109
1:20	Average %	95
	Range %	91-99
1:40	Average %	85
	Range %	81-92

Recovery

The recovery of human PLA2 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)	92	88-96
EDTA plasma (n=4)	97	93-101

Target Background

Function (From Uniprot)	Secretory calcium-dependent phospholipase A2 that primarily targets dietary phospholipids in the intestinal tract. Hydrolyzes the ester bond of the fatty acyl group attached at sn-2 position of phospholipids (phospholipase A2 activity) with preference for phosphatidylethanolamines and phosphatidylglycerols over phosphatidylcholines. May play a role in the biosynthesis of N-acyl ethanolamines that regulate energy metabolism and inflammation in the intestinal tract. Hydrolyzes N-acyl phosphatidylethanolamines to N-acyl lysophosphatidylethanolamines, which are further cleaved by a lysophospholipase D to release N-acyl ethanolamines. May act in an autocrine and paracrine manner. Upon binding to the PLA2R1 receptor can regulate podocyte survival and glomerular homeostasis. Has anti-helminth activity in a process regulated by gut microbiota. Upon helminth infection of intestinal epithelia, directly affects phosphatidylethanolamine contents in the membrane of helminth larvae, likely controlling an array of phospholipid-mediated cellular processes such as membrane fusion and cell division while providing for better immune recognition, ultimately reducing larvae integrity and infectivity.
