Stilbenes

 

Stilbenes belongs belongs to the group of estrogens (or oestrogens) are primary female sex hormones and play an important role in the regulation of many physiological processes of the reproductive system, such as ovulation, fertilization, implantation of the embryo and lactation. They can be produced synthetically and are used as a medication. Some estrogens are used as steroids. If animals are treated with estrogens, drug residues may remain in the animal’s meat and milk. Our reliable test systems can detect estrogen residues.
