Based on the request from teachers attending the "Separation of DNA by electrophoresis" workshop organized by the Centre for Promoting Science Education of the Chinese University of Hong Kong in 2003, the Department of Biochemistry will supply the apparatus and reagents for conducting the DNA electrophoresis experiment in secondary schools.
|
This kit offers a series of activities to learn the principles of electrophoresis. After learning the basic technique, teachers/students progress to using agarose gel electrophoresis to separate mixtures of molecules. The Gel Electrophoresis Unit is a home made plastic tank with cables but without power supply. Remember that a power supply that can deliver at least 40V (better performance can be obtained if the voltage is between 60-100V) is necessary for the DNA electrophoresis experiment. |
