Descrizione generale

Amyloid β (Aβ) 1-42 is the major Aβ species in the amyloid plaques that develop in the case of Alzheimer′s disease (AD). It has a cross-β structure with parallel, in-register β-sheets.

Applicazioni

Amyloid β 1-42 rat has been used as an amyloid β (Aβ) oligomer in intracerebroventricular (ICV) injection/intra-hippocampal infusion to establish the Alzheimer′s disease (AD) model in rat.

Azioni biochim/fisiol

Amyloid β 1-42 forms amyloid fibrils more readily compared to Aβ(1–40), in vitro. Aβ1-42 injections are known to cause brain dysfunction indicating learning and memory deficits. Amyloid β (Aβ) refers to peptides derived from amyloid precursor protein that vary in length from 37–43 amino acids. 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.

    1 answer

    1. This product has not been tested for solubility or in vitro use. However there are publications available that may be helpful. Please see the information and links to the articles below:

      Aβ1-42 was dissolved in sterile water at a concentration of 2 mmol/L and incubated at 37 °C for 24 h.
      https://www.nature.com/articles/aps2013203

      A solution of 200 ng/μL concentration of Aβ was prepared in PBS (0.1 M). The solution of Aβ was incubated for 5 days at 37⁰C, and before injection, PBS was added to the solution to reach a final concentration of 10 ng/μL.
