Lecirelin, a synthetic gonadotropin-releasing hormone (GnRH) analogue, acts as a GnRH agonist. Lecirelin is widely used for the research of bovine ovarian follicular cysts[1].

In Vitro

Lecirelin (2.07 μM) significantly increases the tension and frequency of contractions in preovulatory follicles (PF), small follicular cysts (FC-S), and large follicular cysts (FC-L)[1].
Lecirelin increases the strips from preovulatory follicles contract significantly more than strips from cysts[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
