Description

Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Biochem/physiol Actions

Testosterone secreted by the testis is converted to dihydrotestosterone in the target tissues where it appears to mediate many of the biological actions of testosterone. Androgens direct the development of the male phenotype during embryogenesis and at puberty.

Preparation Note

Testosterone dissolves in chloroform at 100 mg/ml to yield a clear, colorless to very faint yellow solution. It is also soluble in methanol, absolute ethanol (0.5 mg/ml), 45 percent (w/v) aqueous 2-hydroxypropyl-b-cyclodextrin (18.2 mg/ml), vegetable oils and dioxane. It is slightly soluble in methyl oleate and insoluble in water.

Application

Testosterone has been used as a standard to study the developmental profile of steroid hormones in male and female rat brains. This hormone has also been used to evaluate its effects on muscle mass and signaling in mice.
