β-Amyloid (12-28) (TFA) (Amyloid β-Protein (12-28) (TFA)) is a peptide fragment of β-amyloid protein (β1-42). β1-42, a 42 amino acid protein , is the major component of senile plaque cores. β-Amyloid (12-28) (TFA) shows aggregation properties. β-Amyloid (12-28) (TFA) has the potential for Alzheimer’s disease research [1] .
