| GDF11

Growth differentiation factor 11 (GDF11), also known as bone morphogenetic protein 11 (BMP-11), is a protein that in humans is encoded by the growth differentiation factor 11 gene.GDF11 is a member of the Transforming growth factor beta family.GDF11 acts as a cytokine and its sequence is highly conserved between in humans, mice and rats.The bone morphogenetic protein group is characterized by a polybasic proteolytic processing site, which is cleaved to produce a protein containing seven conserved cysteine residues.
 

| 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)	1000	500	250	125	62.5	31.25	15.62	0
OD	2.35	1.35	0.8	0.48	0.34	0.26	0.22	0.09
Corrected OD	2.26	1.26	0.71	0.39	0.25	0.17	0.13	-

 

| Repeatability

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

| Recovery

The recovery of Rat GDF11 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)	84-103	98
Plasma(n=8)	92-105	102
Cell Culture Supernates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Rat GDF11 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 (%)	87-103	87-108	105-115
	Average (%)	92	98	108
