Progesterone is a steroid hormone which plays an important role in the preparation for and maintenance of pregnancy. It is synthesized from cholesterol via pregnenolone, then rapidly metabolized to pregnanediol, for the most part, in the liver. The ovary and placenta are the major production sites; but a small amount is also synthesized by the adrenal cortex in both men and women. Circulating progesterone levels, which are characteristically low during the follicular phase, increase sharply during the luteal phase of menstrual cycles, reaching a maximum some 5 to 10 days after the midcycle LH peak. Unless pregnancy occurs, a steep decline to follicular levels sets in about 4 days before the next menstrual period.Progesterone is produced in the ovaries (specifically after ovulation in the corpus luteum), the adrenal glands (near the kidney), and, during pregnancy, in the placenta. Progesterone is also stored in adipose (fat) tissue.

Principle of the Assay: This assay employs a two-site sandwich ELISA to quantitate PROG in samples. An antibody specific for PROG has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPROG present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PROG is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PROG bound in the initial step. The color development is stopped and the intensity of the color is measured.

PROG n/a

Samples: Serum, Plasma, Other biological fluids
Assay Type: Sandwich. Sample Volume: 1-200 uL
Precision: Intra-assay Precision (Precision within an assay)
Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays)
Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.
CV (%) = SD/meanX100
Intra-Assay: CV
Inter-Assay: CV
Detection Wavelength: 450 nm. Elephant Progesterone (PROG) ELISA Kit or ELISA (enzyme-linked immunosorbant assays) Kits in general, are a valuable research tool for a myriad of applications in a range of scientific settings. Currently, three major types of ELISA formats are used by researchers: sandwich, competitive and indirect. Most commercially available ELISA Kits are sandwich or competitive. Commercially available ELISA Kits contain wells that have been pre-coated with the capture antibody. Please refer to the product manual for the ELISA format of your specific kit.
