| IFN-β

Interferon beta is a protein that is encoded by the IFNB1 gene.The natural and recombinant protein forms have antiviral, antibacterial, and anticancer properties.Interferon beta 1a (tradenames: Avonex and Rebif) and Interferon beta 1b (tradenames: Betaseron/Betaferon) are used as drugs.
 

| 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)	1000	500	250	125	62.5	31.2	15.6	0
OD	2.04	1.49	0.97	0.63	0.41	0.29	0.24	0.09
Corrected OD	1.95	1.4	0.88	0.54	0.32	0.2	0.15	-

 

| Repeatability

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

| Recovery

The recovery of Pig IFN-β 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)	84-101	96
Cell Lysates(n=8)	93-105	102

 

| Linearity

Samples were spiked with high concentrations of Pig IFN-β 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	88-96
	Average (%)	91	93
1 : 4	Range (%)	89-103	87-108
	Average (%)	94	98
