Product Name: Progesterone, 17 -a Hydroxy-

Category: Fertility

Sample Type: Serum

Sensitivity: 0.05 ng/mL

Description: An unknown amount of 17-a-OHP present in the sample and a fixed amount of 17-a-OHP conjugated with horse-radish peroxidase compete for binding.

Introduction: The GenWay 17-a-OH Progesterone Enzyme Immunoassay Kit provides materials for the quantitative determination of 17-a-OH Progesterone in serum.
This assay is intended for research use only .
The steroid 17-a-Hydroxyprogesterone (17- a -OHP) is produced by both the adrenal cortex and gonads. Even though 17-a-OHP has relatively little progestational activity, it is of intense clinical interest because it is the immediate precursor to 11-desoxycortisol (Cpd-S). Because Cpd-S is produced by 21-hyUroxytation of 17-o-0HP, measu rement of 17--o-0HP is a useful indirect ind icator of 21.hydroxylase activity. In congenital 21hydroxyl ase deficiency, the most common variety of congenital adrena l hyperplasia (CAH), 17-a-OHP is secreted in abund ant excess. It is moderately elevated in the 11-f!-hydroxylase deficiency as well. Measurement of 17-a-OHP is therefore valuable in the initial diagnosis of CAH.

Principle of the test: The GenWay 17-a-OH Progest erone ELISA Kit is a solid phase enzyme-linked immunosorbent assay (ELISA), based on the principle of competitive binding.
The microtite- wells are coated with a poIyclonal antibody directed towards an antigenic site on the 17-a-O HP molecule. Endogenous 17-a-OHP of a patient sample competes with a 17-a-OHP-horseradish peroxidase conjugate for binding to the coated antibody. After incubation the unbound conjugate is washed off.
The amount of bound peroxidase conjugate is inversely proportional to the concentration of 17-a-O HP in the sample. After addition of the substrate solution, the intensity of color developed is inversely proportional to the concentration of 17-a-O HP in the patient sample.

Storage and Stability: When stored at 2-8C unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
Opened reagents must be stored at 2-8C. Microtiter wells must be stored at 2-8C. Once the foil bag has been opened, care should be taken to close tightly again. Opened kits retain activity for six weeks if stored as described above.
