Introduction:

Intended use:
RIDASCREEN® 17ß-Östradiol is a competitive enzyme immunoassay for the quantitative analysis of 17ß-estradiol in bovine plasma.

General information:
17β-estradiol is a natural sexual hormone. The levels of 17β-estradiol in bovine plasma from peripheral blood are very low. In calves not more than 1 - 2 pg/ml are present and in cycling females the concentration of 17&beta-estradiol is 1 - 5 pg/ml.
Only in plasma of pregnant animals or in plasma of animals illegally treated with anabolic agents, levels in the range of 100 to 1000 pg/ml can be found.
