| HYOU1

Hypoxia up-regulated protein 1 is a protein that is encoded by the HYOU1 gene.The protein encoded by this gene belongs to the heat shock protein 70 family. This gene has three mRNAs from the use of alternative transcription sites. A cis-acting segment is found at the 5' end of exon 1A which is involved in the stress-dependent induction. The transcript that begins with exon 1B is preferentially induced by hypoxia, resulting in the accumulation of this protein in the endoplasmic reticulum (ER).
 

| 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	2.36	1.78	1.23	0.79	0.46	0.29	0.17	0.09

| Repeatability

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

| Recovery

The recovery of Human HYOU1 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)	92-106	103
Tissue Homogenates(n=8)	97-108	105

 

| Linearity

Samples were spiked with high concentrations of Human HYOU1 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	88-97	90-111
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-114
	Average (%)	94	98	107
