| SDF-1

The stromal cell-derived factor 1 (SDF-1), also known as C-X-C motif chemokine 12 (CXCL12), is a chemokine protein that is encoded by the CXCL12 gene on chromosome 10.It is ubiquitously expressed in many tissues and cell types.Stromal cell-derived factors 1-alpha and 1-beta are small cytokines that belong to the chemokine family, members of which activate leukocytes and are often induced by proinflammatory stimuli such as lipopolysaccharide, TNF, or IL1. The chemokines are characterized by the presence of 4 conserved cysteines that form 2 disulfide bonds. They can be classified into 2 subfamilies.

| 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	2.23	1.31	0.9	0.62	0.43	0.32	0.26	0.1
Corrected OD	2.13	1.21	0.8	0.52	0.33	0.22	0.16	-

| Repeatability

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

| Recovery

The recovery of Human SDF-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)	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 Human SDF-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 (%)	84-95	88-95	90-110
1 : 2	Average (%)	91	92	96
1 : 4	Range (%)	89-103	87-108	105-115
1 : 4	Average (%)	94	98	108
