The OLIS Cary-16 instrument is located in Clement 122. Circular dichroism (CD) is often used to assess the three-dimensional shapes of proteins. The Cary-16 is an older CD instrument, but it has been modernized recently by an upgrade done by OLIS. Students learn how to use this instrument in Physical Biochemistry (Chem-316). Research students working with Professors Curran and Prigodich also use this instrument.
