| OAS3

2'-5'-oligoadenylate synthetase 3 is an enzyme that is encoded by the OAS3 gene. This gene encodes an enzyme included in the 2', 5' oligoadenylate synthase family. This enzyme is induced by interferons and catalyzes the 2', 5' oligomers of ATP. These oligomers activate latent RNase L, leading to degradation of both viral and endogenous RNA. This enzyme family plays a significant role in the inhibition of cellular protein synthesis in response to viral infection.
 

| 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	0.625	0.312	0.156	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 Human OAS3 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)	84-100	96
Plasma(n=8)	92-105	102
Tissue Homogenates(n=8)	96-108	104

 

| Linearity

Samples were spiked with high concentrations of Human OAS3 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 (%)	84-95	88-96	90-110
	Average (%)	90	93	96
1 : 4	Range (%)	89-103	87-107	105-115
	Average (%)	94	98	108
