Notice: the ICE Office will be closed through Monday, July 13th.

Due to UW-Madison campus access restrictions the ICE office will remain closed through July 13. The ICE Online Store will reopen on July 13 but only for limited service because of the restricted access to our facilities. Beginning July 13 ICE will process and ship SMALL orders once a week. We will aim for a processing time of 5-10 business days from receipt of order to shipping, operating within the constraints of very limited access. We apologize for any inconvenience and thank you for your patience and understanding as we work through a partial re-opening. If you have questions, please contact us by email at iceorders@chem.wisc.edu. We will try to respond within 48 hours.

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.
