As the world’s largest provider of amyloid peptides, AnaSpec has always been on the forefront in the development of novel solutions for amyloid-related research. We are
pleased to announce our latest breakthrough—the industry’s first commercially available beta-amyloid peptides for sequences 1-44, 1-45, 1-46, 1-47, 1-48, and 1-49.
Amyloid Precursor Protein, APP, is predominantly processed by a-Secretase, producing a 83-amino acid C-terminal fragment, C83; while a small amount is processed by
b-Secretase, producing a 99-amino acid C-terminal fragment, C99. Subsequent cleavages of C83 and C99 by g-Secretase produce a 3-kD (p3) protein in the former and a
4-kD (b-amyloid) protein in the latter and a CT57-59 in both fragments.1 The 4-Kd consists of Ab which are 39 to 42 amino acids in length, with Ab 1-42 being
the major component of amyloid plaques which accumulates in neurons of Alzheimer’s disease brain.2,3 Novel cleavage sites (e and z) downstream of the
g–cleavage site have recently been reported,4,5 which release longer Abs (1-43, 1-45, 1-46 and 1-48).
These longer Abs have been notoriously difficult to make, due to a C-terminus sequence composed primarily of hydrophobic amino acids. Drawing on years of experience
synthesizing difficult peptides, AnaSpec is pleased to add these latest Abs to our catalog. With this recent addition, the world’s largest collection of amyloid peptides
keeps getting bigger.

Beta-Amyloid (1-40) and Beta-amyloid (1-42) Sampler Kits:
Fluorophore labeled beta-amyloid peptides have been used in investigating beta-amyloid's aggregation, generation and clearance, microglial activation and phagocytosis.
These sampler kits provide a broad selection of peptides for researchers interested in beta-amyloid related experiments.
DHL™ fluorescent beta-amyloid (1-40) & (1-42) sampler kits contain a total of 6 beta-amyloid peptides, including:
Two unlabeled control peptides
A biotin labeled beta-amyloid peptide
Three beta-amyloid peptides with different fluorophore conjugates
