CRF, bovine is a potent agonist of CRF receptor, and displaces [125I-Tyr]ovine CRF with a Ki of 3.52 nM.

IC50 & Target

Ki: 3.52 nM (CRF receptor)[1]

In Vitro

CRF, bovine is a potent agonist of CRF receptor, and displaces [125I-Tyr]ovine CRF with a Ki of 3.52 nM[1]. CRF shows pEC50s of 11.16, 8.53 and 8.70 for human CRF1, human CRF2 and rat CRF[2]. CRF is released from hypothalamic-pituitary-adrenal (HPA) axis induced by stress, and leads to production of glucocorticoids which down regulate immune responses. CRF also has proinflammatory effects. CRF affects brain microvessel endothelial cells (BMEC) structure or function, CRF (100 nM) significantly increases cAMP in BMEC[3].

Cell Assay

CRF (1 μM) is added to the cell cultures that are further incubated for 5, 15 and 30 min at 37°C. Control cells are incubated with medium only. Following incubation time, cells are lysed directly on the growth dish using the detergent provided by the cAMP enzyme immunoassay kit. Following trypan blue staining to ensure complete lysis, the cell lysate is collected and assayed for cAMP. In some cases, the brain microvessel endothelial cells (BMEC) are treated with forskolin or pretreated either with the CRFR antagonist Antalarmin (1 μM) or the ATP analogue 2′5′-deoxyadenosine for 5 min at 37°C[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
