UMass Amherst

Welcome to the home page of BMB 695a,
Methods in Macromolecular Crystallography (Spring 2007)!

The UMass protein crystallography home page has moved to

This journal club is organized by Scott Garman, Jeanne Hardy, and Karsten Theis.We share a common interest in structural biology, including X-ray crystallographic techniques. Our labs are all located on the 10th floor of Lederle Tower, along with the X-ray diffraction facility.

If you are looking for the home page of the UMass X-ray diffraction facility, you can find it here.

If you are looking for Karsten Theis' home page, it is here, while Scott Garman's home page is here, and Jeanne Hardy's is here.

Pictures of the UMass Macromolecular X-ray Diffraction facility open house are here.

Spring 2007 Journal Club Schedule (Biochem 695a, Methods in Macromolecular Crystallography):

Journal Club meets Fridays at 8:45 in 1030 LGRT. Participants can pick a paper on their own or talk to Jeanne, Karsten or Scott. Download files by following the links below.
