Support of 7th International Conference on Partitioning in Aqueous two-phase Systems - Advances in Separations in Bio- chemistry, Cell Biology & Biotechnology

生物材料的分离方法可以非常灵敏和大规模地分离生物材料，同时保持在非变性环境中，这是各种科学学科中非常感兴趣的。因此，双水相聚合物体系中的分配技术通常是蛋白质、核酸和细胞的研究和商业纯化的首选方法。近年来出版了三本关于分区的书籍和数百篇论文，以及美国、欧洲和日本的几家大公司对分区的商业、大规模应用，揭示了这种方法的巨大潜力和对它的兴趣。由于分区技术的迅速发展，自1979年以来每两年举行一次国际会议。第七届双水相体系分配国际会议将于1991年6月2-7日在新奥尔良举行。这是十多年来第一次在美国举行会议，预计将吸引一批不同学科和背景的顶尖科学家。除分离外，大会与会者通常还涉及各种生物技术分离，因此，大会还包括以下会议：新颖和相互竞争的分离技术、对分离和相关过程的引力效应、聚乙二醇化化学的生物技术应用、以及聚合物-蛋白质和聚合物-表面化学。这笔赠款用于部分支持旅费、注册费和每日津贴。至少另外两个联邦机构(NASA和ONR)和几家工业公司也部分支持这次会议。

Separation methods by which biological materials may be isolated with great sensitivity and in large scale, while remaining in a nondenaturing environment, are of substantial interest in a variety of scientific disciplines. Consequently the technique of partitioning in two-phase aqueous polymer systems is frequently the method of choice for both research and commercial purifications of proteins, nucleic acids, and cells. The great potential of the method and interest in it is revealed by the publication in recent years of three books and hundreds of papers on partitioning and by the commercial, large-scale application of partitioning by several major companies in the U.S., Europe, and Japan. As a result of the rapidly expanding development of partitioning techniques, international conferences have been held biannually since 1979. The 7th International Conference on Partitioning in Aqueous Two-Phase Systems will be held in New Orleans, June 2- 7, 1991. This is the first time in over a decade for the meeting to be held in the United States and it is expected to attract a group of leading scientists of varied disciplines and backgrounds. The Conference participants are typically involved in a variety of biotechnical separation in addition to partitioning, and as a consequence the Conference includes sessions on: novel and competing separation technologies, gravitational effects on separation and related processes, biotechnical applications of PEG chemistry, and polymer- protein and polymer-surface chemistry. The grant is used for partial support of travel, registration, and per diem. At least two other federal agencies (NASA and ONR) and several industrial companies also partial support of this conference.
