Abstract excerpt
The fibrillogenic properties of Alzheimer's A beta peptides corresponding to residues 1-40 of the normal human sequence and to two mutant forms containing the replacement Ala21 to Gly or Glu22 to Gln were compared. At pH 7.4 and 37 degrees C the Gln22 peptide was found to aggregate and precipitate from solution faster than the normal A beta, whereas the Gly21 peptide aggregated much more slowly. Electron...
