beta-Amyloid (1-42) menschlich

Beschreibung:
Beta-Amyloid (1-42) ist ein Peptidfragment, das von dem amyloidvorläuferprotein (APP) abgeleitet ist und hauptsächlich mit der Alzheimer-Krankheit assoziiert wird. Dieses Peptid besteht aus 42 Aminosäuren und ist bekannt für seine Neigung zur Aggregation, wodurch unlösliche Fibrillen entstehen, die zur Bildung von Amyloid-Plaques im Gehirn betroffener Personen beitragen. Der Aggregationsprozess wird von verschiedenen Faktoren beeinflusst, darunter pH-Wert, Temperatur und das Vorhandensein von Metallionen. Beta-Amyloid (1-42) zeichnet sich durch seine hydrophobe Natur aus, die seine Selbstassemblierung zu Oligomeren und Fibrillen erleichtert. Man glaubt, dass diese Aggregate die Zellfunktion stören und Neurotoxizität fördern, was zu kognitivem Abbau führt. Die CAS-Nummer 107761-42-2 identifiziert dieses Peptid spezifisch, das häufig in der Forschung verwendet wird, um die Mechanismen der Alzheimer-Krankheit zu untersuchen und potenzielle therapeutische Strategien zu entwickeln. Seine Rolle in der Neurodegeneration macht es zu einem wichtigen Fokus sowohl in der Grundlagenforschung als auch in der klinischen Forschung, die darauf abzielt, die Alzheimer-Krankheit zu verstehen und zu behandeln.

  • Amyloid β-Protein (1-42) (HFIP-treated)

    CAS:
    The peptide was obtained by dissolving Amyloid β-Protein (1-42) in HFIP, aliquoting, and removing the solvent as described in the literature. The morphology of the resulting peptide was studied by transmission electron microscopy (TEM). The magenta arrow points to the nucleation centers where aggregation starts. The yellow arrow indicates the fibrils which are formed as long thin helical structures with regular twists. See in the technical note.

  • Amyloid β-Protein (1-42)

    CAS:
    Aβ 1-42, 42-residue fragment of amyloid precursor protein, has been found to be a major constituent of the senile plaques formed in the brains of patients with Alzheimer’s disease and late Down’s syndrome. Aβ 1-42 readily forms neurotoxic oligomers at physiological pH. On the other hand, the peptide shows antimicrobial activity. The sequence of this peptide corresponds to the sequence of human, bovine, canine, feline, ovine, guinea pig, and rabbit Aβ42. The peptide has been used to detect amyloid β-protein multimers in the cerebrospinal fluid of Alzheimer’s disease patients through fluorescence correlation spectroscopy. For detailed descriptions of the preparation of Aβ 1-42 monomers and protofibrils please see the papers of Jan, Hartley, and Lashuel, Stine et al. (2011), and of Broersen and colleagues. For the preparation of Aβ for experimental use, Fezoui et al. (2000) found that solvation of synthetic peptide with sodium hydroxide (Aβ·NaOH) followed by lyophilization, produced stocks with superior solubility and fibrillogenesis characteristics. Solubilization of the pretreated material with neutral buffers resulted in a pH transition from ≈10.5 to neutral, avoiding the isoelectric point of Aβ (pI≈5.5), at which Aβ precipitation and aggregation propensity are maximal.

    CAS:
    <p>Amyloid β-peptide (Aβ) has been identified as the key subunit of the extracellular plaques found in the brains of patients with Alzheimer's disease (AD) and Down's syndrome (DS). Aβ has therefore been extensively studied as a potential target for treatment of AD.Aβ is formed from the cleavage of the large, transmembrane protein- APP (amyloid precursor protein). Cleavage of APP by β- and then γ-secretases results in the formation of Aβ. Aβ can aggregate to produce amyloid-β oligomers, which are thought to be highly neurotoxic. Over time Aβ can further aggregate to produce the characteristic senile plaques present in AD and DS.Aβ can be degraded by enzymes such as neprilysin, insulin degrading enzyme or endothelin converting enzyme. At physiological levels Aβ may be involved in controlling synaptic activity and neuronal survival.Supplied as the TFA salt</p>

  • Amyloid beta-Protein (1-42) sodium salt

    CAS:
    <p>Amyloid β-Protein (1-42) is a fragment of the amyloid beta protein that is thought to be a major contributor to the development of Alzheimer's disease. Amyloid β-Protein (1-42) has been shown to have neuroprotective effects, as it reduces cell death in the brain and preserves memory. It binds to the β-catenin protein in neurons and protects against oxidative stress by reducing production of reactive oxygen species. This molecule also reduces microglia activation and tnf-α levels, which may reduce inflammation. Amyloid β-Protein (1-42) is found in plants such as pueraria lobata, and has been used for centuries in traditional Chinese medicine for its anti-inflammatory properties.</p>

  • Amyloid beta-Protein (Human, 1-42)

    CAS:
    Amyloid beta-protein (Aβ) is a peptide that is found in the human brain. It is one of the major components of amyloid plaque, which are deposits of a protein fragment in the brain that form as a result of aging and Alzheimer’s disease. It is produced by cleavage of the amyloid precursor protein (APP). Aβ has been shown to be toxic to cells, causing them to die. This toxicity may be due to its ability to inhibit ATP production and increase oxidative stress. Aβ can also induce apoptosis by binding to receptors on cell surfaces and activating intracellular signaling pathways. These events lead to activation of caspases, which are proteolytic enzymes that contribute to programmed cell death.
