일반 설명
Amyloid β Protein Fragment 1-40 (Aβ40) is derived from the amyloid-β protein (Aβ), which is mapped to human chromosome 21q21.3. Aβ40 is predominantly present in the vascular amyloid deposits. Aβ40 comprises of C-terminal membrane insertion domain. It shows structural transition from random coil to a α-helical structure in a water-micelle medium.
애플리케이션
Amyloid β Protein Fragment 1-40 has been used:
- in the temperature based conformational studies using Fourier transform infrared/differential scanning calorimetry (FT-IR/DSC) studies
- as a reference standard in sandwich-type enzyme immunoassay for quantifying amyloid A4 protein in cerebrospinal fluid of patients with head trauma
- as a component of embryonic stem cell medium to inhibit amyloid deposition in fibroblasts
생화학적/생리학적 작용
Amyloid β Protein Fragment 1-40 (Aβ40) forms cation based ion channels.
Amyloid β-protein is neurotrophic and neurotoxic in vivo and in vitro in human and rat neuronal cell cultures. β-Amyloid peptides (amino acids 1-42 and 1-43) are the major constituents of senile plaques and neurofibrillary tangles that occur in the hippocampus, neocortex, and amygdala of patients with Alzheimer′s disease.
