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

This Aβ40 construct places a long-chain biotin group on an added C-terminal lysine rather than at the Aβ N terminus. The 6-carbon spacer improves accessibility for avidin binding and provides a C-terminally tagged alternative for affinity assays.

• streptavidin capture
• C-terminal Aβ probe design
• amyloid binding studies
• surface immobilization

LifeTein current TDS verifies a 0.1 mg catalog form, MW 4797.5 and >95% purity. N-terminal and C-terminal biotinylated Aβ peptides should not be treated as interchangeable.
