Instructional Equipment to Improve Undergraduate Molecular and Cellular Biology Laboratories

为了给学生提供细胞结构和功能关键方面的实验知识，本系在其细胞和分子生物学课程中增加了实验室练习。首次提供与分子遗传学结合的实验室工作；微生物学增加了一个分子遗传学项目；细胞生物化学、呼吸和光合作用的改进实验被引入细胞生理学和生物化学实验室。这些实验室的改进需要通过该项目提供的新设备。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冷冻室，水浴，凝胶照相装置，分析天平，台式高压灭菌器，凝胶染色过程的轨道平台摇床，微处理器控制的紫外可见分光光度计，组织均质机，还有氧气监测系统。有了这个设备，学生可以对以前只通过讲座和阅读学习的领域进行调查。新的实验室活动使细胞生物学的理论和实验理解的结合成为可能，为他们追求生命科学的高级学位和职业生涯提供了必要的准备。受资助机构将从非联邦来源获得等额的NSF奖励。

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.
