Background: Testosterone

Testosterone is an important secreted androgen synthesized from cholesterol-derived pregnenolone. Circulating testosterone is predominantly bound to proteins, including specific sex hormone binding globulin (SHBG) and nonspecific proteins such as albumin. It is believed that bioavailable testosterone includes the free steroid and the albumin-bound form. Testosterone is the main androgen secreted by the Leydig cells of the testes and affects both primary and secondary sexual development.

FAQs for Testosterone Antibody (4E1G2) [Alexa Fluor® 488]

Showing  1 - 1 of 1 FAQ Showing All
  • Q: Does R&D Systems® Testosterone Parameter Assay Kit, Catalog # KGE010, detect free or total testosterone?

    A: 'Free' testosterone is typically defined as testosterone which is bioavailable, and not bound to sex hormone binding globulin (SHBG). Interference testing performed by spiking SHBG into testosterone-containing samples, demonstrates interference in testosterone detection with Catalog # KGE010, when the concentration of SHBG is greater than 100 ng/ml. (For further details on interference testing, please refer to the "Specificity" section in the product insert.) Assays for 'total' testosterone measure both 'free' testostrone as well as testosterone bound to SHBG. Since KGE010 does not detect testosterone bound to SHBG, this assay does not measure 'total' testosterone.
