| IGF-1

Insulin-like growth factor 1 (IGF-1), also known as growth hormone C, is a hormone with a molecular structure similar to insulin. IGF-1 is produced primarily by the liver and is stimulated by growth hormone (GH).Most of IGF-1 is bound to one of 6 binding proteins (IGF-BP). The IGF-1 receptor and insulin receptor are two closely related members of a transmembrane tetrameric tyrosine kinase receptor family. They control vital brain functions, such as survival, growth, energy metabolism, longevity, neuroprotection and neuroregeneration.
 

| 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)	50	25	12.5	6.25	3.12	1.56	0.78	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 Duck IGF-1 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
Cell Culture Supernates(n=8)	95-108	104

 

| Linearity

Samples were spiked with high concentrations of Duck IGF-1 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 (%)	84-94	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-109	105-115
	Average (%)	94	98	109
