- (Asn⁶⁷⁰,Leu⁶⁷¹)-Amyloid β/A4 Protein Precursor₇₇₀ (667-675)CAS: 150234-52-9
SEVNLDAEF corresponds to the mutant junctional sequence of the amyloid precursor protein (APP) found in a Swedish family with early-onset Alzheimer's disease, therefore referred to as the 'Swedish' mutation (K670N/M671L). The peptide has been used for assaying cleavage at leucine-aspartate by cathepsin G and chymotrypsin, whereas neither cathepsin B, D nor L generated any products.
- (Pyr³)-Amyloid β-Protein (3-40)CAS: 161818-04-8
The pyroglutamate-modified amyloid-β peptides derived from Aβ40 (H-7422) and Aβ42 (H-4796) have gained considerable attention as potential key participants in the pathology of Alzheimer's disease (AD) due to their abundance in AD brain, high aggregation propensity, stability, and cellular toxicity. Aβ40 and 42 can be N-terminally truncated by action of cathepsin B. The cyclization of Glu³ is catalyzed by glutaminyl cyclase. Hence, inhibition of these enzymes could be a therapeutic approach to AD.
- Abz-(Asn⁶⁷⁰,Leu⁶⁷¹)-Amyloid β/A4 Protein Precursor₇₇₀ (669-674)-EDDnpCAS: 1007306-20-8
Intramolecularly quenched fluorescent substrate containing the ortho-aminobenzoyl (Abz) / N-(2,4-dinitrophenyl)ethylenediamine (EDDnp) groups as the donor / acceptor pair. It corresponds to the Swedish-mutated (JMV2236) β-amyloid precursor protein (βAPP) sequence targeted by β-secretase BACE (β-site APP-cleaving activity). This FRET substrate is more selectively cleaved by BACE1 and BACE2 than by cathepsin D, a disintegrin and metalloprotease 10 (ADAM10), tumor necrosis α-converting enzyme (TACE), presenilin-1 (PS1), or presenilin-2 (PS2).
- Abz-Amyloid β/A4 Protein Precursor₇₇₀ (669-674)-EDDnpCAS: 1802078-43-8
Intramolecularly quenched fluorescent substrate containing the ortho-aminobenzoyl (Abz) / N-(2,4-dinitrophenyl)ethylenediamine (EDDnp) groups as the donor / acceptor pair. It mimicks the wild-type (JMV2235) β-amyloid precursor protein (βAPP) sequence targeted by β-secretase BACE (β-site APP-cleaving activity). This FRET substrate is cleaved by BACE1, BACE2, and cathepsin D.
