Testosterone (mouse/rat) ELISA Kit

Testosterone (mouse/rat) ELISA Kitis available at Gentaur for Next week Delivery.

Sensitive, Colorimetric Assay.

Description:

Testosterone is the most important androgen secreted into the blood. In males, testosterone is secreted primarily by the Leydig cells of the testes; in females ca. 50% of circulating testosterone is derived from peripheral conversion of androstenedione, ca. 25% from the ovary and ca. 25% from the adrenal glands. In women, high levels of testosterone are generally found in hirsutism and virilization, polycystic ovaries, ovarian tumors, adrenal tumors and adrenal hyperplasia. In men, high levels of testosterone are associated to the hypothalamic pituitary unit diseases, testicular tumors, congenital adrenal hyperplasia and prostate cancer. Low levels of testosterone can be found in patients with the following diseases: Hypopituitarism, Klinefelter’s syndrome, Testicular feminization, or chidectomy and Cryptorchidism, enzymatic defects and some autoimmune diseases. BioVision’s Testosterone EIA kit is based on the principle of competitive binding between Testosterone in the test specimen and Testosterone-HRP conjugate for a constant amount of rabbit anti-Testosterone. In the incubation, goat anti-rabbit IgG-coated wells are incubated with 25 μl of Testosterone standards, controls, samples, 100 μl Testosterone-HRP conjugate reagent and 50 μl rabbit anti-testosterone reagent at room temperature for 60 min. During the incubation, a fixed amount of HRP-labeled Testosterone competes with the endogenous Testosterone in the standard, sample, or quality control serum for a fixed number of binding sites of the specific Testosterone antibody. Thus, the amount of Testosterone peroxidase conjugate immunologically bound to the well progressively decreases as the concentration of Testosterone in the specimen increases. Unbound Testosterone peroxidase conjugate is then removed and the wells are washed. Next, a solution of TMB Reagent is then added and incubated at room temperature for 15 min., resulting in the development of blue color. The color development is stopped with the addition of stop solution, and the absorbance is measured spectrophotometrically at 450nm.

Applications: This ELISA kit is used for quantitative protein detection, establishing normal range.
