Featured Beta-Amyloid and Amylin Peptides

Order Amylin (1-37), human at the discounted price.

Beta-Amyloid (Aβ or Abeta) is a peptide processed from amyloid precursor protein (APP). Beta-amyloid is typically a 39-43 amino acid peptide derived from the extracellular and transmembrane regions of APP. APP is expressed as several isoforms, including proteins of 695, 751, and 770 amino acids.

Beta-amyloid plays a central role in information processing in the brain, and abnormal amyloid deposition is a major histopathological hallmark of Alzheimer’s disease. Aβ40 and Aβ42 are widely studied because of their association with neurotoxicity and amyloid plaque formation in Alzheimer’s disease and related disorders.


Featured LPETG and Sortase Motif Peptides

LPETG and LPXTG motif peptides are widely used in sortase-mediated ligation, protein labeling, and site-specific conjugation workflows. LifeTein offers biotinylated, fluorescently labeled, and modified LPETG peptides for research applications.
