一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
促黑素释放抑制因子的化学式为C13H24N4O3,是一个三肽,氨基酸序列为H2N-Pro-Leu-Gly-amide,分子量为284.35。促黑素释放抑制因子也被称为Pro-Leu-Gly-NH2、Melanostatin、MSH释放抑制激素或MIF-1,是来源于催产素裂解的内源性多肽片段,在体内通常发挥多种不同的活性(1)。MIF-1产生多种效果,例如阻断阿片受体激活的效应(2)、充当D2和D4多巴胺受体亚型的正向变构调节剂、抑制其他神经肽如α-MSH的释放和增强褪黑素活性(3)。MIF-1对血液代谢具有抗性,可以轻易穿过血脑屏障,它的口服活性较差,通常采用注射的方式用药。
