| FoxO3

Forkhead box O3, also known as FOXO3 or FOXO3a, is a protein encoded by the FOXO3 gene.FOXO3 belongs to the O subclass of the forkhead family of transcription factors which are characterized by a distinct fork head DNA-binding domain. There are three other FoxO family members in humans, FOXO1, FOXO4 and FOXO6. These transcription factors share the ability to be inhibited and translocated out of the nucleus on phosphorylation by proteins such as Akt/PKB in the PI3K signaling pathway (aside from FOXO6, which may be constitutively nuclear).Other post-translational modifications including acetylation and methylation are seen and can result in increased or altered FOXO3a activity.

| Repeatability

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

| Recovery

The recovery of Mouse FoxO3 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)	96-107	104

 

| Linearity

Samples were spiked with high concentrations of Mouse FoxO3 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)
1 : 2	Range (%)	84-95
	Average (%)	91
1 : 4	Range (%)	89-103
	Average (%)	94
