| FGF-20

Fibroblast growth factor 20 is a protein which is encoded by the FGF20 gene.The protein is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development,cell growth, morphogenesis, tissue repair, tumor growth and invasion. This gene was shown to be expressed in normal brain, particularly the cerebellum. The rat homolog is preferentially expressed in the brain and able to enhance the survival of midbrain dopaminergic neurons in vitro.
 

| 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 (pg/mL)	800	400	200	100	50	25	12.5	0
OD	2.19	1.71	1.2	0.74	0.48	0.32	0.21	0.07
Corrected OD	2.12	1.64	1.13	0.67	0.41	0.25	0.14	-

 

| Repeatability

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

| Recovery

The recovery of Human FGF-20 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
Cell Culture Supernates(n=8)	96-108	104

 

| Linearity

Samples were spiked with high concentrations of Human FGF-20 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	84-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	98	108
