E2 - Implants Estradiol
Belma implants consist of a polymer reservoir surrounded by a hormone diffusion-controlling membrane. They are designed to release daily doses of a hormone to produce physiological or pharmacological plasma concentrations in mice and rats.
Two oestradiol implants have been developed. The first one makes it possible to achieve pre-ovulatory plasma concentrations and is used mainly in hormone-dependent cancer animal models to support tumour cell growth. The second one (E2 Light) makes it possible to deliver pro-oestrous doses and is designed for gynaecological models (e.g., endometriosis).
