本文介绍了等电点—离子交换法提取谷氨酸的实验方案,该实验方案是在作者与学生不断摸索中形成的,在此与同行分享,希望大家能提出宝贵意见和建议,将该实验不断完善进而推广开来,为高职教育的转型贡献自己的一份力量。在生物制品提取的课程中,等电点沉淀法和离子交换法是现代生物制品生产中的一种重要方法,为了让学生更好的掌握其原理和操作,作者将等电点—离子交换法提取 This article describes the isoelectric point - ion exchange method for the extraction of glutamic acid experimental program, the experimental program is in the continuous exploration of the author and the students formed, here to share with colleagues, I hope everyone can come up with valuable comments and suggestions, the experiment Continue to improve and then promote it, contributing to the transformation of higher vocational education in their own part. In the course of biological product extraction, isoelectric point precipitation and ion exchange are important methods in the production of modern biological products. In order to better understand the principle and operation of the students, the isoelectric point-ion exchange extract
