HDExaminer

Sierra Analytics is pleased to present HDExaminer, a complete software solution for bottom-up H-D Exchange MS data analysis.

"This is the best analysis software I have used thus far."
-Laura Busenlehner, University of Alabama

HDExaminer provides powerful functionality to give a comprehensive picture of the deuteration uptake behavior of a protein. This information can be used to help determine protein folding behavior, protein-drug interactions, and other useful results.
