Heterotypic seeding of Tau fibrillization by pre

Genetic, clinical, histopathological and biomarker data strongly support Beta-amyloid (Aβ) induced spreading of Tau-pathology beyond entorhinal cortex (EC), as a crucial process in conversion from preclinical cognitively normal to Alzheimer's Disease (AD), while the underlying mechanism remains unclear. In vivo preclinical models have reproducibly recapitulated Aβ-induced Tau

Human beta Amyloid (1-42) PTD Recombinant Protein (03-111)

Target Information Beta amyloid is a 4043 amino acid peptide cleaved from amyloid precursor protein by a protease, gamma-secretase. Beta Amyloid (1-40) (Amyloid beta 40 or Abeta 40) together with beta Amyloid (1-42) (Amyloid beta 42 or Abeta 42) are two major C-terminal variants of the amyloid beta protein, constituting the majority of amyloid beta proteins.

Interrogating Amyloid Aggregates using Fluorescent Probes

Amyloids are a broad class of proteins and peptides that can misfold and assemble into long unbranched fibrils with a cross-β conformation. These misfolding and aggregation events are associated with the onset of a variety of human diseases, among them, Alzheimer's disease, Parkinson's disease, and Huntington disease. Our understanding of amyloids has been greatly

Polyalanine and Abeta Aggregation Kinetics Probing

The aggregation of proteins into stable, well-ordered structures known as amyloid fibrils has been associated with many neurodegenerative diseases. Amyloid fibrils are long straight, and un-branched structures containing several proto-filaments, each of which exhibits "cross beta structure,"- ribbon-like layers of large beta sheets whose strands run perpendicular to the fibril axis.

Protein aggregation Wikipedia

Protein aggregation is a biological phenomenon in which intrinsically disordered proteins or mis-folded proteins aggregate (i.e., accumulate and clump together) either intra- or extracellularly. Mis-folded protein aggregates are often correlated with diseases. In fact, protein aggregates have been implicated in a wide variety of disease known as amyloidoses, including ALS,
