| IL-18

Interleukin-18 (IL-18), also known as interferon-gamma inducing factor is a protein which in humans is encoded by the IL18 gene.[5][6] The protein encoded by this gene is a proinflammatory cytokine. Many cell types, both hematopoietic cells and non-hematopoietic cells, have the potential to produce IL-18.It was first described in 1989 as a factor that induced interferon-γ (IFN-γ) production in mouse spleen cells.IL-18 can modulate both innate and adaptive immunity and its dysregulation can cause autoimmune or inflammatory diseases.
 

| 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)	500	250	125	62.5	31.25	15.62	7.81	0
OD	2.36	1.78	1.23	0.79	0.46	0.29	0.17	0.09
Corrected OD	2.27	1.69	1.14	0.7	0.37	0.2	0.08	-

 

| Repeatability

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

| Recovery

The recovery of Bovine IL-18 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)	80-101	97
Plasma(n=8)	90-105	101
Cell Culture Supernates(n=8)	95-108	106

 

| Linearity

Samples were spiked with high concentrations of Bovine IL-18 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 (%)	84-96	88-96	90-110
	Average (%)	91	94	98
1 : 4	Range (%)	89-103	87-109	105-115
	Average (%)	95	92	111
