, Preface
This manual is designed to aid the laboratory instructor in preparing for, supervising, and
analyzing experiments in Experimental Biochemistry: A Hands On Approach. The text
was written with the idea of its application to a wide variety of biochemistry lab courses.
Whether your course is for non-majors and meets only once a week for 3 hours, or is a
more intensive course requiring several meetings, you should be able to find the
appropriate length and intensity of experiments. Many of the experiments are suitable for
a survey course and can stand alone. For those interested in a comprehensive approach,
there are groups of experiments that do make an integrated package. Many of the
techniques used offer both types of experiment. For example, chapter 7 involves gel
filtration chromatography. Experiment 7 is a stand alone experiment involving estimating
the molecular weight of myoglobin with Sephadex G-75. Experiment 7a is part of the
comprehensive purification of lactate dehydrogenase and uses gel filtration on Sephadex
G-150 or Sephacryl S-200 as the final purification step.
Each chapter of this manual corresponds to the same chapter in Experiments in
Biochemistry and includes the following:
Estimated time required by competent and prepared students
Materials needed for the experiment and sources when necessary
Hints for the preparation of reagents and equipment, and pitfalls to avoid
Suggestions for disposal and clean up of experiments
Sample data the students are likely to see and answers to the end of experiment
calculations
Answers to the additional problem sets.
We hope that armed with this manual you will find the implementation of the
experiments straight forward. If you ever have trouble, please feel free to contact the
author (see Tech Support).
