| NRP2

Neuropilin 2 (NRP2) is a protein that is encoded by the NRP2 gene.This gene encodes a member of the neuropilin family of receptor proteins. NRP2 is expressed by a wide variety of cell types. The transmembrane protein has been reported to bind to SEMA3C, SEMA3F, VEGF-A, VEGF-C, VEGF-D, TGFβ, integrins and ANGPTL4 to promote downstream signaling pathways. Consequently, NRP2 is known to play a role in cardiovascular development, axon guidance, tumorigenesis, inflammation and cardiovascular disease.Multiple transcript variants encoding distinct isoforms have been identified for this gene.
 

| 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	0.62	0.31	0.15	0
OD	2.14	1.63	1.16	0.78	0.57	0.43	0.24	0.07
Corrected OD	2.07	1.56	1.09	0.71	0.5	0.36	0.17	-

 

| Repeatability

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

| Recovery

The recovery of Human NRP2 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)	84-101	96
Plasma(n=8)	92-105	102
Tissue Homogenates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human NRP2 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 (%)	84-95	88-96	90-110
	Average (%)	90	93	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	98	108
