Testosterone ELISA Kit (Rat/Mouse)


Rat/mouse testosterone ELISA kit is a competitive immunoassay which is designed for detecting quantitative levels of mouse or rat testosterone in plasma or serum samples. This assay has a minimum sensitivity detection limit of 0.066 ng/ml.


Testosterone (17beta-hydroxy-4-androstene-3-one) belongs to the androgen family, which is composed of a C19 steroid containing keto and hydroxyl groups and it is one of the most effective natural hormones. It is synthesised in the Leydig cells that can be found in the testes in males, the ovaries in females and in the adrenal glands for both sexes. The biosynthesis of testosterones has been found to coincide with the spermatogenesis and fetal Leydig cell differentiation in the male rat, also the capacity of Leydig cells to produce and secrete testosterone is far higher in young when compared to older rats. Testosterone is also known to be secreted during late gestational and neonatal periods which can cause significant level of brain sexual dimorphism in rats. It can exert a number of varying influencing over sexual behaviour, cardiovascular health, overall energy, bone integrity, muscle strength and mass. The primary role of testosterone is in developing secondary male sex characteristics and it can be also be useful in evaluating the hypogonadal states. High levels of testosterone in males has been associated with congenital adrenal hyperplasia, hypothalamic pituitary unit diseases, prostate cancer and testicular tumors. Whereas in females, high concentration are linked to polycystic ovaries, ovarian tumors, hirsutism, adrenal tumors and adrenal hyperplasia.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

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.

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.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
