RIDASCREEN® 17β-Ӧstradiol is a competitive enzyme immunoassay for the quantitative analysis of 17β-estradiol in bovine plasma.
All reagents required for the enzyme immunoassay - including standards - are contained in the test kit.
For in vitro use only.
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 17β-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.
