Human amyloid-beta (1-40) peptide

Supplier: Cayman Chemical

Amyloid-β (1-40) peptide Aβ (1-40) is a 40-residue protein fragment of the C-terminal portion of the β-amyloid protein implicated in Alzheimer’s disease. Aβ (1-40) is more abundant, less neurotoxic, and does not form oligomers as easily as amyloid-β (1-42) peptide (Aβ (1-42).

Poly-L-lysine hydrobromide

Supplier: SIGMA ALDRICH MICROSCOPY

Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.
