Instructional Equipment to Improve Undergraduate Molecular and Cellular Biology Laboratories

为了向学生提供细胞结构和功能关键方面的实验知识，该系在其细胞和分子生物学课程中增加了实验室练习。第一次与分子遗传学一起提供实验室工作；在微生物学中增加了一个分子遗传学项目；细胞生理学和生物化学实验室正在引入改进的细胞生物化学、呼吸和光合作用实验。这些实验室的改进需要通过该项目提供的新设备。该设备包括：凝胶电泳和印迹设备、测序凝胶读取器、两台离心机、冰箱、-70*C冰柜、水浴、凝胶摄影单元、分析天平、桌面高压灭菌器、用于凝胶染色程序的轨道平台振荡器、微处理器控制的UV-可见光分光光度计、组织匀质器和氧气监测系统。有了这种设备，学生可以对以前只能通过讲座和阅读才能学习的领域进行调查。新的实验室活动使对细胞生物学的理论和实验的了解成为可能，这为他们在生命科学领域追求更高的学位和职业生涯提供了必不可少的准备。接受资助的机构正在将NSF的奖励与从非联邦来源获得的同等金额相匹配。

To provide students with experimental knowledge of key aspects of cellular structure and function, this department is adding laboratory exercises to its cellular and molecular biology programs. Laboratory work is being provided for the first time in conjunction with Molecular Genetics; a project in molecular genetics is being added to Micro- biology; improved experiments in cellular biochemistry, respiration, and photosynthesis are being introduced into the Cellular Physiology and Biochemistry laboratories. These laboratory improvements required the new equipment that is being provided through this project. The equipment includes: gel electrophoresis and blotting equipment, a sequencing gel reader, two centrifuges, a refrigerator, a -70*C freezer, water baths, a gel photographic unit, an analytical balance, a table-top autoclave, an orbital platform shaker for gel staining procedures, a microprocessor- controlled UV-visible spectrophotometer, a tissue homogenizer, and oxygen-monitoring systems. With this equipment, students can do investigations in areas previously studied only through lectures and reading. The combination of theoretical and experimental understanding of cellular biology made possible by the new laboratory activities provides preparation essential to their pursuit of advanced degrees and careers in the life sciences. The grantee institution is matching the NSF award with an equal sum obtained from non-Federal sources.
