| FGF2;bFGF

Fibroblast growth factor 2 (FGF-2), also known as basic fibroblast growth factor (bFGF) and FGF-β, is a growth factor and signaling protein encoded by the FGF2 gene.It binds to and exerts effects via specific fibroblast growth factor receptor (FGFR) proteins, themselves a family of closely related molecules. Fibroblast growth factor protein was first purified in 1975; soon thereafter three variants were isolated: 'basic FGF' (FGF2); Heparin-binding growth factor-2; and Endothelial cell growth factor-2. Gene sequencing revealed that this group is the same FGF2 protein and is a member of a family of FGF proteins.
 

| 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)	200	100	50	25	12.5	6.25	3.12	0
OD	2.36	1.78	1.23	0.79	0.46	0.29	0.17	0.09
Corrected OD	2.27	1.69	1.14	0.7	0.37	0.2	0.08	-

 

| Repeatability

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

| Recovery

The recovery of Pig FGF2;bFGF 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)	88-104	97
Plasma(n=8)	94-107	104
Cell Culture Supernates(n=8)	96-110	104

 

| Linearity

Samples were spiked with high concentrations of Pig FGF2;bFGF 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 (%)	82-93	88-96	90-110
	Average (%)	90	93	97
1 : 4	Range (%)	89-103	87-110	105-115
	Average (%)	94	99	109
