| PLA2G12B

Phospholipase A2, Group XIIB (PLA2G12B) belongs to the phospholipase A2 (PLA2) group of enzymes, which function in glycolipid hydrolysis with the release of free fatty acids and lysophospholipids. This family member has altered phospholipid-binding properties and is catalytically inactive. The protein is secreted, and together with microsomal triglyceride transfer protein, it functions to regulate HNF4alpha-induced hepatitis C virus infectivity.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (ng/mL)	10	5	2.5	1.25	0.625	0.312	0.156	0
OD	2.17	1.74	1.17	0.78	0.47	0.32	0.23	0.08
Corrected OD	2.09	1.66	1.09	0.7	0.39	0.24	0.15	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Human PLA2G12B spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	83-101	96
Plasma(n=8)	92-105	102
Tissue Homogenates(n=8)	96-108	103

 

| Linearity

Samples were spiked with high concentrations of Human PLA2G12B and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Tissue Homogenates(n=4)
1 : 2	Range (%)	85-95	88-96	90-110
	Average (%)	90	93	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	97	108
