Notice: the ICE Online Store and Office will be closed through January 2021.

The ICE office will be closed from September 4, 2020 until January 4, 2021. Due to the COVID-19 pandemic we are unable to ship orders during the fall 2020 semester. We apologize for any inconvenience and thank you for your patience and understanding. Questions or inquiries about kits or publications should be sent to iceorders@chem.wisc.edu. If you have questions, please contact us by email at iceorders@chem.wisc.edu. We will check and respond to emails twice a week during the closure.


DNA Optical Transform (X-Ray Diffraction) Kit

DNA Optical Transform (X-Ray Diffraction) Kit

0
Type: CP, D, I    |    Level: AP, Coll
$29.00

Simulate Rosalind Franklin's famous X-ray ­diffraction experiments that led to the discovery of the DNA double helix with a laser pointer and the two-dimensional diffraction pattern transparencies from the DNA Optical Transform (X-Ray Diffraction) Kit.

The kit includes a manual with background information and directions, a diffraction pattern transparency, and projection masters. A source of visible laser light is not included, but any laser pointer will work. The comprehensive manual provides an overview of the DNA structure solution and diffraction principles; an optical transform demonstration; student experiment; and background information in reprints of two articles from the Journal of Chemical Education.

Your students can participate as well with additional DNA Optical Transform (X-Ray Diffraction) Transparencies that can be purchased individually or in sets of 5 or 10.

Simulate X-ray diffraction using a visible laser and two-dimensional patterns on a transparency with the Optical Transform (X-Ray Diffraction) Kit.

Note, as of January 2011 the DNA Diffraction Transparencies have been updated. The new transparencies are laser photo plotted at a higher resolution which allows us to better model the true structure of B-DNA. As a result you will find that the diffraction pattern of B-DNA (cell J) is different from that produced by the old diffraction transparencies, but is a more accurate representation of DNA's structure. The manual has been updated accordingly; please refer to it for more information.
