Amyloid β-peptide fragment; minimum section required to bind to brain proteins. Binds with high affinity to α7-nicotinic ACh receptors, and impairs memory retention following central administration in mice in vivo.
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.
