Beta-Amyloid (1-40)-Lys(Biotin)-NH2

This Aβ40 derivative adds a biotinylated lysine at the C terminus and terminates the construct as an amide. It provides an affinity-tagged Aβ40 reagent whose N terminus remains unmodified.

• C-terminally tagged Aβ studies
• streptavidin capture
• amyloid binding assays
• comparative terminal-modification studies

The C-terminal amide and Lys(Biotin) are part of the exact chemistry. LifeTein current TDS verifies MW 4685.4 and ≥95% purity for the 0.1 mg form; price is left TBD.
