| sfxn4

Sideroflexin-4 is encoded by SFXN4.This gene encodes a member of the sideroflexin family. The encoded protein is a transmembrane protein of the inner mitochondrial membrane, and is required for mitochondrial respiratory homeostasis and erythropoiesis.SFXN4 (Sideroflexin 4) is a Protein Coding gene. Diseases associated with SFXN4 include Combined Oxidative Phosphorylation Deficiency 18 and Combined Oxidative Phosphorylation Deficiency. Among its related pathways are Respiratory electron transport and Complex I biogenesis. Gene Ontology (GO) annotations related to this gene include monoatomic cation transmembrane transporter activity and monoatomic ion transmembrane transporter activity. An important paralog of this gene is SFXN5.
 

| 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.

| Repeatability

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

| Recovery

The recovery of Human sfxn4 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	95
Plasma(n=8)	92-106	103
Cell Culture Supernates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human sfxn4 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 (%)	84-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-113
