Description

Amyloid-β (Aβ) is a peptide cleavage product of amyloid precursor protein (APP) that is often used as a biomarker in Alzheimer’s disease. Misfolded Aβ oligomers instigate conformation changes in other, normally folded Aβ oligomers, increasing the number of misfolded proteins and eventually forming neurotoxic plaques. These plaques impair cognitive performance in vivo. Aβ (1-42) is more fibrillogenic and more highly associated with Alzheimer’s disease than Aβ (1-40), although the shorter form is more common.

Custom Order

  • Size of single unit expressed as number (e.g. '500' in the case of 500 mg)
  • Total quantity of unit size desired (e.g. '10' in the case of 10 x 500 mg). If only one unit is desired, you may leave this blank.
  • This field is for validation purposes and should be left unchanged.
