β-amyloid (12-28) TFA, a peptide fragment of β-amyloid protein (β1-42), is the major component of senile plaque cores. β-amyloid (12-28) has aggregation properties and the potential for Alzheimer's disease research.
β-Amyloid (1-42), rat TFA is a 42-aa peptide, shows the effects of cytotoxicity on acute hippocampal slices, and has been used in studies of alzheimer's disease.
