- 产品描述
- 17-alpha hydroxy Progesterone BioAssay ELISA Kit is a C-21 steroid hormone produced in the adrenal gland and gonads, during the synthesis of glucocorticoids and sex steroids. It is derived from progesterone via 17-hydroxylase, a P450c17 enzyme, or from 17-hydroxypregnenolone via 3ß-hydroxysteroid dehydrogenase/?5-4 isomerase. 17a -OHP has no defined physiologic role except as a precursor molecule. Serum 17a -OHP levels are age-dependent, with peak levels observed during fetal life and the immediate postnatal period. During the first week of life, serum 17a -OHP levels fall ~50-fold as compared to cord blood values. A small transient increase occurs in male infants 30-60 days postnatally. Levels for both sexes remain at constant low levels during childhood, and then progressively increase during puberty reaching adult levels of ~100ng/dl (~3.03nmol/l). As with cortisol, serum 17a -OHP levels normally have an ACTH-dependent diurnal variation, with peak levels in the morning and a nadir at night.In addition, ovarian production of 17a -OHP increases during the luteal phase of the menstrual cycle. 17-hydroxyprogesterone is a natural progestin and in pregnancy increases in the third trimester primarily due to fetal adrenal production. Normal levels are 3-90ng/dl in children and in women, 15-70ng/dl prior to ovulation, and 35-290 ng/dl during the luteal phase. Measurements of levels of 17-hydroxyprogesterone are useful in the evaluation of patients with suspected congenital adrenal hyperplasia as the typical enzymes that are defective, namely 21-hydroxylase and 11ß-hydroxilase, lead to a build-up of 17OHP. In contrast, the rare patient with 17a-hydroxylase deficiency will have very low or undetectable levels of 17OHP. Elevated serum 17 a -OHP levels at baseline and/or after ACTH stimulation have also been reported in other forms of adrenal hyperplasia.Intended Use:Competitive immunoenzymatic colorimetric method for quantitative determination of 17α OH Progesterone concentration in serum and plasmaPrinciple of the Test:17alpha-OH Progesterone (antigen) in the sample competes with horseradish peroxidase 17alpha-OH Progesterone (enzyme-labelled antigen) for binding onto the limited number of anti-17alpha-OH Progesterone coated on the microplates (solid phase).After incubation, the bound/free separation is performed by a simple solid-phase washing. The enzyme substrate (H2O2) and theTMB-substrate (TMB) are added. After an appropriate time has elapsed for maximum colour development, the enzyme reaction is stopped and the absorbances are determined. 17alpha-OH Progesterone concentration in the sample is calculated based on a series by a set of standard. The colour intensity is inversely proportional to the 17alpha-OH Progesterone concentration in the sample.Detection Range: 0-19.2ng/mlSpecificity: 100%Sensitivity: 0.1ng/mlKit Components:Microtiter Plate, 1x96wellsTMB Substrate, 1x15mlStop Solution, 1x15mlStandard 0, 1x1mlStandard 1, 1x1mlStandard 2, 1x1mlStandard 3, 1x1mlStandard 4, 1x1mlStandard 5, 1x1mlControl, 1x1mlConjugate (HRP), 1x6mlStorage and Stability:Store all components at 4°C.
