Required Text: Ninfa & Ballou. Fundamentals Laboratory Approaches for Biochemistry and Biotechnology, Fitzgerald Science Press (1998)

Attendance: Attendance in the laboratory is required. You can not pass this course if you miss 3 or more labs. Since the introductory lecture at the beginning of each laboratory includes safety hazards and protocols as well as experimental procedures, you must be present for the introductory lecture. Many reagents have short lifetimes, are expensive, and must be made specifically for each laboratory experiment. Thus experiments may not be made up.

Supplies: Approved Eye-Protection (see safety regulations) and a bound Laboratory Notebook are required. Nitrile goves, Sharpie™ markers or equivalent, and a lab coat are recommended. I will provide used floppy disks for free upon request.
