Amyloid β-Peptide (1-42) (human)

Lyophilized White solid, with no soy flavor, no protein denaturation, acidic non-precipitation, heating does not coagulate, easily soluble in water, good fluidity, and other good processing properties, is an excellent health food material.

Amyloid β-Peptide (1-42) (human)[107761-42-2], a major component of amyloid plaques, accumulates in neurons of Alzheimer's disease brains. Aβ(s) peptides, their peptide fragments and mutated fragments are used to study a wide range of metabolic and regulatory functions including activation of kinases, regulation of cholesterol transport, function as a transcription factor, and regulators of inflammation. Aβ(s) peptides and their peptide fragments are also used to study oxidative stress, metal binding and mechanisms of protein cross-linking in the context of diseases such as Alzheimer's disease and neurodegeneration.

Amyloid beta (Aβ or Abeta) is a peptide of 36-C43 amino acids that is processed from the Amyloid precursor protein. Amyloid β-Peptide (1-42) human is a 42-amino acid peptide which plays a key role in the pathogenesis of Alzheimer disease. Beta-Amyloid (1-42) human is used as follows:
for the production of Aβ-1-42 oligomer;
in western blot analysis;
for interference testing of immunomagnetic reduction (IMR) plasma Aβ42 assay;
to study the effect of resveratrol on Aβ-1-42-induced impairment of spatial learning, memory, and synaptic plasticity;
to investigate the effect of Aβ in epithelial cell cultures.

Amyloid β Protein is produced from amyloid-β precursor protein (APP). It consists of two C terminal variants, such as a long tailed Aβ 1-42 and a short tailed Aβ 1-40. APP is located on human chromosome 21q21.3.

Amyloid β-Peptide (1-42) (human) is a human form of the predominant amyloid β-peptide found in the brains of patients with Alzheimer's disease. Amyloid β Protein Fragment 1-42 (Aβ 1-42) has antioxidant and neuroprotective properties. Accumulation of amyloid β Protein is associated with Alzheimer′s disease (AD) and Down Syndrome. Aβ 1-42 regulates cholesterol transport and may function as a transcription factor. It may possess anti-inflammatory and antimicrobial properties. Downregulates bcl-2 and increases the levels of bax. Neurotoxic.
