Archive of SEPGuides (5.1.2017): DNA Extraction Kit

Kit Description (kit updated Jan 2014)

4 Kits Available

1 Crate per Kit

The DNA Extraction Kit offers students a chance to see DNA! Students isolate DNA from strawberries or onions, and then collect the DNA by spooling it onto wooden sticks. The kit also contains procedures for isolating DNA from other tissues as well as activities for teaching students how DNA is packaged in the cell, the concept of the genetic code, and DNA sequencing.

NOTE:  Teacher supplies onion or fruit, ethanol, and ice. Frozen thymus is available from SEP upon request.

January 2014: added small funnels (20) and supplies for strawberry DNA extraction. Removed older resources, X ray sequencing films. Added GATTACA DVDs.

Additional Resources

"At the Bench is the unique and hugely successful handbook for living and working in the laboratory, an essential aid to understanding basic lab techniques and how research groups work at a human level."

Examples of DNA models we like are under the yellow tab for Molecular Modeling, select Models and Model Kits.
