| TECK;CCL25

Chemokine (C-C motif) ligand 25 (CCL25) is a small cytokine belonging to the CC chemokine family that is also known as TECK (Thymus-Expressed Chemokine). CCL25 is believed to play a role in the development of T-cells.It is chemotactic for thymocytes, macrophages, and dendritic cells. CCL25 elicits its effects by binding to the chemokine receptor CCR9.Human CCL25 is produced as a protein precursor containing 151 amino acids. The gene for CCL25 (scya25) is located on human chromosome 19.
 

| 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)	5000	2500	1250	625	312.5	156.25	78.12	0
OD	2.14	1.21	0.81	0.53	0.39	0.3	0.25	0.09
Corrected OD	2.05	1.12	0.72	0.44	0.3	0.21	0.16	-

 

| Repeatability

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

| Recovery

The recovery of Mouse TECK;CCL25 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)	84-102	96
Plasma(n=8)	92-106	103
Tissue Homogenates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Mouse TECK;CCL25 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Tissue Homogenates(n=4)
1 : 2	Range (%)	84-96	89-96	90-110
	Average (%)	91	94	96
1 : 4	Range (%)	89-104	87-108	105-115
	Average (%)	94	98	108
