| E2

Estradiol (E2), also called oestrogen, oestradiol, is an estrogen steroid hormone and the major female sex hormone.Estradiol is produced within the follicles of the ovaries and in other tissues including the testicles, the adrenal glands, fat, liver, the breasts, and the brain. Estradiol is produced in the body from cholesterol through a series of reactions and intermediates.The major pathway involves the formation of androstenedione, which is then converted by aromatase into estrone and is subsequently converted into estradiol. Alternatively, androstenedione can be converted into testosterone, which can then be converted into estradiol.

| Repeatability

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

| Recovery

The recovery of Zebrafish E2 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)	81-101	96
Plasma(n=8)	92-105	101
Cell Culture Supernates(n=8)	97-108	105

 

| Linearity

Samples were spiked with high concentrations of Zebrafish E2 and diluted with Universal Diluent to produce samples with values within the range of the assay.

	Average (%)	91	93	96
1 : 4	Range (%)	89-104	87-108	105-115
