Three types of mutant SOD1 (Apo-AS pH3 1 M guanidine, Apo-AS pH3, and Apo-A4V pH7) were studied using the atomic force microscope and a Veeco fluid cell. The fluid cell set up was tested thoroughly and the imaging was optimized by using a silicon cantilever. Sample 1, Apo-AS pH3 1 M guanidine AFM images, showed very large amorphous aggregates, ranging from about 400 to 10,000 nm in length. Sample 2, Apo-AS pH3 images also contained amorphous aggregates, with the most particles per image ranging from 300 to 1,200 nm in length. Sample 3, Apo-A4V pH7 imaged particles, appear to be mainly amorphous aggregations with the least particles per image and a length ranging from 600 to 1,400 nm.
