Figure 2

Scanning electron microscopy (SEM) images of (A) EPRP of α-chymotrypsin (0 percent trehalose) precipitated into n -propanol (magnification: 5000 ×); (B) EPRP of α-chymotrypsin (5 percent trehalose) precipitated into n -propanol (magnification: 5000 ×); (C) PCMC of α-chymotrypsin (40 percent trehalose) precipitated into n -propanol (magnification: 5000 ×). SEM was carried out on a Zeiss EVO50 scanning electron microscope. Samples were dried by rinsing with anhydrous propanol, placed on a sample holder, and coated with silver before being scanned in vacuo.
