| ATF3

Activating Transcription Factor 3 (ATF3) also know as cyclic AMP-dependent transcription factor is a protein that,is encoded by the ATF3 gene.ATF-3 is induced upon physiological stress in various tissues.It is also a marker of regeneration following injury of dorsal root ganglion neurons, as injured regenerating neurons activate this transcription factor. Functional validation studies have shown that ATF3 can promote regeneration of peripheral neurons, but is not capable of promoting regeneration of central nervous system neurons.
 

| 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	2.6	1.74	1.07	0.66	0.43	0.31	0.23	0.09
Corrected OD	2.51	1.65	0.98	0.57	0.34	0.22	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 ATF3 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)	92-105	102
Plasma(n=8)	96-109	105

 

| Linearity

Samples were spiked with high concentrations of Human ATF3 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)
1 : 2	Range (%)	88-96	92-110
	Average (%)	93	96
1 : 4	Range (%)	87-108	105-115
	Average (%)	98	109
