By harnessing one of the most common, but elusive, structures in nature - the alpha helical peptide, we believe that we can dramatically improve the treatment of these diseases and positively impact the lives of millions of patients.
At 3 [degrees] C, most of the protein is in its alpha helical shape, and the crystals grow in only one direction, forming long columns.
