Biological Activity

[Description]:

[Tyr0] Corticotropin Releasing Factor, ovine is a corticotropin releasing factor/hormone isolated from ovine. Corticotropin releasing factor (CRF) is a hypothalamic hormone, stimulates the release of adrenocorticotropic hormone (ACTH) and of β-endorphin[1][2].

[In Vitro]

[Tyr0] Corticotropin Releasing Factor, ovine has a strong binding effect with plasma protein[1].

[In Vivo]

[Tyr0] Corticotropin Releasing Factor, ovine (328 μCi/μg; 198 pg/min or 225 pg/min; continuous infusions intravenous; single dose lasting 5-7 hr) shows a long plasma half-life and low metabolic clearance rate in male cynomolgus monkeys[1]. Animal Model: Young adult male cynomolgus monkeys (4.0-6.9 kg)[1] Dosage: 10 mL/h for 198 pg/min or 225 pg/min Administration: Continuous infusions intravenous; collected every 60 min during 5-7 hr Result: Showed a longer plasma half-life than for all other known hypothalamic peptides and its metabolic clearance rate was relatively low and considerably less all other known hypothalamic peptides or adreno-cortico-tropic-hormone (ACTH).
