Custom Anaspec® Peptides Handling & Storage information

[Pyr3]-beta-Amyloid: N-terminal pyroglutamate reduces susceptibility to aminopeptidase degradation and may also play an important role in biological function. 26-O-acyl isoA beta (1-42): a ß-amyloid 1-42 isopeptide that undergoes O-N intramolecular acyl migration under physiological conditions. This propeptide, unlike ß-amyloid 1-42, possesses good solubility during HPLC purification as well as in long-term storage as a solution. "HFIP: Removal of any preexisting structures in lyophilized stocks of Aβ-peptide is the critical initial step for controlled aggregation studies. HFIP has been shown to break down β-sheet structure, disrupt hydrophobic forces in aggregated amyloid preparations, and promotes α-helical secondary structure. HFIP treatment of lyophilized Aβ-peptide resulted in a dense, homogeneous preparation of unaggregated peptide and samples can be stored as peptide films. " Sodium salt peptide: prepared by neutralizing the TFA salt form of Aß (1-42) with a dilute sodium hydroxide solution has superior solubility and fibrillogenesis properties, and the fibrils are equally neurotoxic.
