Attributs du produit: The Progesterone Immunoassay kit is designed to quantitatively measure Progesterone present in extracted dried fecal samples, urine and tissue culture media samples. A progesterone standard is provided to generate a standard curve for the assay. Standards or diluted samples are pipetted into a clear microtiter plate coated with an antibody to capture mouse antibodies. A progesterone-peroxidase conjugate is added to the standards and samples in the wells. The binding reaction is initiated by the addition of a monoclonal antibody to progesterone to each well. After a 2 hour incubation the plate is washed and substrate is added. The substrate reacts with the bound progesterone-peroxidase conjugate. After a short incubation, the reaction is stopped and the intensity of the generated color is detected in a microtiter plate reader capable of measuring 450nm wavelength.

Préparation de l'échantillon:

Dried Fecal samples We have a detailed Extraction Protocol available on our website at: www.arborassays.com/ resources/#protocols. The ethanol concentration in the final Assay Buffer dilution added to the well should be <5 % . Urine samples Urine samples should be diluted at least 1:4 times with the provided Assay Buffer. For comparison to creatinine as a urine volume marker please see our NIST-calibrated 2 plate and 10 plate Urinary Creatinine Detection kits, K002-H1 and K002-H5.

Procédure de l'essai:

We recommend that all standards and samples be run in duplicate to allow the end user to accurately determine progesterone concentrations.
1. Use the plate layout sheet on the back page to aid in proper sample and standard identification. Determine the number of wells to be used and return unused wells to the foil pouch with desiccant. Seal the ziploc plate bag and store at 4ºC.
2. Pipet 50 μL of samples or standards into wells in the plate.
3. Pipet 75 μL of Assay Buffer into the non-specific binding (NSB) wells.
4. Pipet 50 μL of Assay Buffer into wells to act as maximum binding wells (Bo or 0 pg/mL).
5. Add 25 μL of the DetectX® Progesterone Conjugate to each well using a repeater pipet.
6. Add 25 μL of the DetectX® Progesterone Antibody to each well, except the nsb wells, using a repeater pipet.
7. Gently tap the sides of the plate to ensure adequate mixing of the reagents. Cover the plate with the plate sealer and shake at room temperature for 2 hours. If the plate is not shaken signals bound will be approximately 45 % lower.
8. Aspirate the plate and wash each well 4 times with 300 μL wash buffer. Tap the plate dry on clean absorbent towels.
9. Add 100 μL of the TMB Substrate to each well, using a repeater pipet. 10. Incubate the plate at room temperature for 30 minutes without shaking. 11. Add 50 μL of the Stop Solution to each well, using a repeater pipet. 12. Read the optical density generated from each well in a plate reader capable of reading at 450 nm. 13. Use the plate reader's built-in 4PLC software capabilities to calculate progesterone concentration for each sample.

Calcul des résultats:

Average the duplicate OD readings for each standard and sample.
Create a standard curve by reducing the data using the 4PLC fitting routine on the plate reader, after subtracting the mean OD's for the NSB.
The sample concentrations obtained, calculated from the %B/B0 curve, should be multiplied by the dilution factor to obtain neat sample values.

Restrictions: For Research Use only

Abstract: Progesterone Produits

Classe de substances: Hormone

Sujet: Progesterone, C H O , also known as P4 (pregn-4-ene-3,20-dione) is a C-21 steroid hormone 21 30 2 involved in the female menstrual cycle, gestation and embryogenesis of humans and other species1. Progesterone belongs to a class of hormones called progestogens, and is the major naturally occurring human progestogen2. Progesterone is an essential regulator of human female reproductive function in the uterus, ovary, mammary gland and brain, and plays an important role in non-reproductive tissues such as the cardiovascular system, bone and the central nervous system3. Progesterone action is conveyed by two isoforms of the nuclear progesterone receptor (PR), PRA and PRB. PRA and B are expressed in a variety of normal breast tissue from humans, rats and mice and is also expressed in breast cancer cells4, 5. Progesterone also has neurotrophic roles in the peripheral nervous system as it activates the growth and maturation of axons and stimulates the repair and replacement of myelin sheaths in regenerating nerve fibres6.
