CRF, bovine is a potent agonist of CRF receptor, and displaces [125I-Tyr]ovine CRF with a Ki of 3.52 nM. Ki: 3.52 nM (CRF receptor)[1]
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 CRF2α[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 experiment: | 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]. |

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
