Rat/Mouse Progesterone ELISA Kit

Full Name: Rat/Mouse Progesterone ELISA Kit
Reactivity: Rat, Mouse
Sample Type: Serum, Plasma
Sensitivity: 0.04 ng/ml


Progesterone is also known as 4-pregnene-3, 20-dione is a C21 steroid hormone. It consists of a double bond between C-4 and C-5 and contains a keto group at the C-3 position. It is a female sex hormone which play a critical role during ovulation, fertility and menopause. The main function is to prepare the endometrium for implanting the blastocytes and for maintaining pregnancy. During pregnancy, progesterone stimulates the formation of the placenta and uterine spiral arteries, increases insensible water and nitrogen excretion. The increased blood vessels in the uterus decrease chances of hemorrhage.

The beginning of menstruation, which starts with the luteinization of follicular cells within a growing follicle on the ovary, is also caused by progesterone. These cells alternately release progesterone and oestrogen. Estrogen then causes the rupture of these growing follicles, releasing an egg from one ovary to be fertilized by sperm in the fallopian tubes. The corpus luteum that forms after ovulation continues to produce progesterone throughout pregnancy and into menopause where it declines significantly over time until its production ceases completely.


Rat/mouse progesterone ELISA kit is designed to quantitatively detect concentrations of mouse or rat progesterone using plasma or serum samples. This assay has a minimum sensitivity detection limit of 0.04 ng/ml.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
