| IL-22

Interleukin-22 (IL-22) is a protein that is encoded by the IL22 gene.IL-22 is an α-helical cytokine. IL-22 binds to a heterodimeric cell surface receptor composed of IL-10R2 and IL-22R1 subunits.IL-22R is expressed on tissue cells, and it is absent on immune cells.Crystallization is possible if the N-linked glycosylation sites are removed in mutants of IL-22 bound with high-affinity cell-surface receptor sIL-22R1. The crystallographic asymmetric unit contained two IL-22-sIL-22R1 complexes.

| 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)	200	100	50	25	12.5	6.25	3.12	0
OD	2.36	1.36	0.8	0.48	0.34	0.28	0.23	0.09
Corrected OD	2.27	1.27	0.71	0.39	0.25	0.19	0.14	-

| Repeatability

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

| Recovery

The recovery of Human IL-22 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)	84-101	96
Plasma(n=8)	92-105	102
Cell Culture Supernates(n=8)	96-108	105

| Linearity

Samples were spiked with high concentrations of Human IL-22 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
1 : 2	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-115
1 : 4	Average (%)	94	98	108
