Classroom Kit – Purification of the Restriction Enzyme EcoRI – For 5 Purifications

ABOUT THIS PRODUCT:
In this experiment, students actually purify the restriction enzyme, Eco RI! This procedure utilizes an ion exchange chromatography step for Eco RI purification. Column fractions are assayed for the enzyme using Lambda DNA and digestion products are identified by agarose gel electrophoresis. Fractions that contain Eco RI are identified and pooled. The total and specific activities are calculated. Recommended for college level courses.

Group Size:
For 5 purifications
