| FOXA2

Forkhead box protein A2 (FOXA2), also known as hepatocyte nuclear factor 3-beta (HNF-3B), is a transcription factor that plays an important role during development, in mature tissues and, when dysregulated or mutated, also in cancer.FOXA2 belongs to a subfamily of the Forkhead box (FOX) transcription factors, the other members being FOXA1 and FOXA3. This subfamily of mammalian FOX proteins was first identified because of their ability to bind DNA in rat liver nuclear extracts. The proteins were therefore originally named hepatocyte nuclear factor 3 alpha, beta and gamma.These transcription factors contain a forkhead domain (also known as the winged-helix domain) flanked by sequences necessary for nuclear localization.Their N- and C-termini are also conserved and serve as transactivation domains.
 

| 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	2.22	1.56	0.92	0.63	0.42	0.25	0.18	0.08
Corrected OD	2.14	1.48	0.84	0.55	0.34	0.17	0.1	-

 

| Repeatability

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

| Recovery

The recovery of Human FOXA2 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)	84-101	95
Cell Lysates(n=8)	92-106	103

 

| Linearity

Samples were spiked with high concentrations of Human FOXA2 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	84-95	88-96
	Average (%)	91	93
1 : 4	Range (%)	89-102	87-108
	Average (%)	94	98
