生物活性
产品描述 |
一种神经肽,在肽能神经元中激活K+电流,ED50为23nM,这种作用具有剂量依赖性。 |
靶点 |
ED50:23nM (K+current) |
体外研究 |
In the molluscan central nervous system,Phe-Met-Arg-Phe,amide (FMRFa) acts on K+channels in sensory,motor-,and neuroendocrine neurones.Phe-Met-Arg-Phe,amide activates a novel K+current that is characterized by a combined voltageand receptor-dependent gating mechanism,with both factors being necessary for opening of the channels.Phe-Met-ArgPhe,amide (1μM) significantly inhibits glucose stimulated (300mg/dL) insulin release (p<0.005) and somatostatin release (p<0.01) from the isolated perfused pancreas.Phe-Met-Arg-Phe,amide (FMRF-NH2) (1 and 10μM) is without effect on glucagon secretion,either in low glucose (50mg/dL),high glucose (300mg/dL),or during arginine stimulation (5mM). |
体内研究 |
Phe-Met-Arg-Phe,amide (FMRFamide) stimulates growth hormone secretion in conscious OVX rats.The presence of PheMet-Arg-Phe,amide-like immunoreactivity in neuronal elements in the hypothalamus suggested a role for this in the hypothalamic control of the anterior pituitary function.The injection of 200ng (313.8 picomoles) of FMRFamide (in 2uL) produces a significantly increased plasma GH 15 min after injection.The GH-increasing effect of 400-800ng (627-1255 picomoles) of FMRFamide is already developed after 5 min and lasted up to 30 min. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
