14、nd an experimental curriculum for going with biochemistry teaching. Its task is to help students to understand and master the basic technical principles and methods in biochemistry, to possess the abilities of analyzing problems and working out solutions independently. By learning this curriculum, t

15、he students should understand the basic experimental principles of spectrophotometry，chromatography, electrophoresis and centrifuge, et al.，master the basic technical skills commonly used with these principles and possess the abilities to apply the skills systematically and to optimize the experimen

16、t conditions. The goal of biochemistry experiment is to make the students strengthen their grasp of the biochemistry theories and to integrate what they have learned with scientific research and clinical application.There are 9 experiments that represent most important areas of biochemistry includin

17、g characterization of proteins and nucleic acid by electrophoresis and spectroscopic or chromatographic analysis. These experiments are essential for a typical one-semester course and are to be revised and updated when necessary. New experiments will be added to this list in the future to cover more

18、 topics of biochemistry and to reflect the many advances in biochemistry. Biochemistry Laboratory Rules1Pre-Laboratory Preparation All students must prepare BEFORE ARRIVING IN THE LABORATORY. The experiments are designed so that they can be carried out with proper advance planning within the four-ho

19、ur laboratory periods. It is expected that students should have a fundamental understanding of the theory and practices pertaining to the experiment before entering the laboratory to conduct these experiments. Biochemical experiments often employ toxic chemicals. For the health and safety of all stu

20、dents, the experimental protocols must be studied and the days activities should be planned in advance. If it becomes obvious that a student is ill-prepared, he or she will not be permitted to continue the experiment. 2Safety Precautions in the Biochemistry LaboratoryAll INJURIES, no matter how mino

21、r, should be reported to the instructor IMMEDIATELY. If you have any questions regarding the safe handling of any biochemical, consult your instructor. 3Strictly follow the experimental procedures. Turn to instructors immediately for help once the laboratory instruments dont work. DONT try to fix th

22、e breakdown by yourself. Proper compensation for loss because of your own fault will be demanded.4Disposal of SolutionsIn most cases the solutions used during the laboratory can be disposed of as directed by laboratory personnel at the end of the period. Any volatile organic solvents should be place

23、d in the hood as directed. Laboratory personnel will then dispose of these solvents.5Solid trashes including waste papers are prohibited to discard into the sink. 6All the glassware should be cleaned immediately after use. And all the reagent bottles and instruments should be placed neatly after use

24、. 7An experiment report should be submitted to the Professor and/or TAs in time. Laboratory Report1Although students will work in pairs for all experiments, each student must turn in an individual laboratory report, written by himself or herself. These reports should be clearly written in ink, typed

25、, or printed and be clear and legible. If mistakes are made, neatly cross them out and enter the corrections nearby. Reports should be written in the third person (e.g., do not use “I” or “we”). STAPLE a Title Page to the top of the report and STAPLE the accompanying graphs, tables, and laboratory n

26、otebook sheets to the back. If the report is not clearly presented, the instructor may return the report without grading it. 2Each laboratory report should consist of: a. Title Page A title page for each experiment is required and should state the title of the experiment, the name of the student, th

27、e dates of the laboratory periods covered, the names of the laboratory partners, and the date that the laboratory report is due. b. ObjectivesStatement of the point of the experiment - in no more than two sentences. c. Procedures DO NOT recapitulate the laboratory protocol. Write in you OWN words. A

28、 clear flowchart of the procedures is recommended. d. Results This section should summarize your observations presented in the form of graphs, calculations, tables, etc. e. Discussion Evaluate your data. Explain what you observed and also why you think the data were as observed. Do not restate proce

29、dures! List possible sites of error. Whenever possible demonstrate your understanding of the theory behind the experiment. Support your results (e.g.: “Using the linear portion of the Absorbance vs. Concentration graph to calculate the slope, it was determined that.”) (Limited to only one page per experiment for experiments 1 - 6 and four pages for experiment 7-9). 3If any laboratory report is not completed and turned in by the end of the quarter, the student maybe receive an Incomplete for the
