Testosterone ELISA Kit
INTENDED USE
Human testosterone ELISA kit is a reliable quantitative procedure for measuring testosterone in human serum and plasma. This assay has a minimum sensitivity detection limit of 0.08 ng/ml.
BACKGROUND
Testosterone (also called 17beta-hydroxy-4-androstene-3-one) is the most effective natural hormone which belong to the androgens family, it is composed of a C19 steroid which contains a keto and hydroxyl groups at the three and seventeen positions respectively and it has a molecular mass of 288.47g/mol. It is one of the most vital androgen that is secreted into the blood.
During circulating, the major part of testosterone known to be bound to plasma proteins such as sex hormone binding globuline (SHBG) and albumin. The major function is in the development of secondary male sex characteristics and its measurements can be helpful in evaluating the hypogonadal states. In males it can be secreted by Leydig cells of the testes and in females more than half of circulating testosterone is derived from peripheral conversion of androstenedione and the remainder is from the ovary and the adrenal glands.
