| IL-8Rα

Interleukin 8 receptor alpha is a chemokine receptor. The protein encoded by this gene is a member of the G-protein-coupled receptor family. This protein is a receptor for interleukin 8 (IL8). It binds to IL8 with high affinity, and transduces the signal through a G-protein-activated second messenger system. IL8RA, IL8RB, which encodes another high affinity IL8 receptor, and IL8RBP, a pseudogene of IL8RB, form a gene cluster in a region mapped to chromosome 2q33-q36. Stimulation of CXCR1 in neutrophils by its primary ligand, Interleukin 8, leads to neutrophil chemotaxis and activation.
 

| 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	2.05	1.5	0.99	0.66	0.45	0.33	0.24	0.08
Corrected OD	1.97	1.42	0.91	0.58	0.37	0.25	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 IL-8Rα spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	84-102	96
Cell Lysates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human IL-8Rα and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	84-95	90-110
	Average (%)	91	96
1 : 4	Range (%)	89-103	105-113
	Average (%)	94	107
