This decapeptide is a hypothalamic hormone that controls the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in the pituitary gland and promotes mating behavior. It stimulates the secretion of gonadotropins after its interaction with specific G-protein-coupled receptors that are present in plasma membranes of pituitary gonadotrophs. In addition to hypophysiotropic effect, it also plays a autocrine/paracrine role in peripheral organs such as prostate, breast and ovary. Luteinizing hormone-releasing hormone is not only a neurohormone but may also function as a neurotransmitter or neuromodulator. | |

各位老师,在用凝集法或去溶剂法制备BSA的纳米微球,查阅相关文献,使用100mg的BSA溶于10ml的去离子水中,配成1wt%的水溶液,然后在磁力搅拌下,以1ml/min或2ml/min的速度加入乙醇40ml。在加入过程中,溶液变成乳白色,然后在加入就逐渐变清凉,但同时有沉淀出现,请问各位实验过程有啥问题啊?采取哪些措施可以避免出现沉定?另外制备纳米颗粒的过程,对BSA有具体的要求吗
我理解就是一个是包裹,一个是镶嵌
微球说白了就是小颗粒,尺寸是微米级的,再小就是纳米球了,微球可以是纯球,也可以不是规则的球,椭圆的也可以.
聚苯乙烯微球就是利用搅拌乳化,电喷雾,共轴液流(气流),膜乳化等方法将聚苯乙烯制备成微米尺寸的颗粒.
