| About this protein | |
| Product name | Amyloid β Peptide(1-40) human (人β-淀粉样蛋白，1-40) |
| Alternative names | β-Amyloid(1-40)；Aβ(1-40)；Aβ40；β-淀粉样蛋白(1-40) |
| Description | Amyloid β Peptide(1-40) human is a 40-residue peptide implicated in the pathogenesis of Alzheimer's disease (AD) and aged Down's Syndrome, which is promoted by the acquisition of an additional copy of chromosome 21. The peptide is a proteolytic product of the much larger amyloid precursor protein (APP) encoded by a gene on chromosome 21. The peptide comprises a large extracellular N-terminal domain and a short hydrophobic membrane-spanning domain, followed by a short C-terminal region. Beta-APP both precedes and forms part of the transmembrane region. |

-20℃或更低温度保存，至少一年有效。由于多肽的每次冻融均会引起部分失活，所以首次配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液)，须分装后-20℃或更低温度冻存，以避免反复冻融。
注意事项：
本产品为冻干粉，由于微量的多肽在冻干过程中沉积在管内，形成很薄或不可见的多肽层，所以在打开管盖前，我们建议在离心机中约8,000-12,000g离心10-30秒，使附着在管盖或管壁上的多肽聚集于管底。
本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗，不得用于食品或药品，不得存放于普通住宅内。

文献和实验Effects of the β-Amyloid Peptide on Membrane Ion Permeability
Several lines of evidence suggest a role for membrane ion channels in the neurotoxic effects of the β-amyloid peptide (Aβ). This chapter describes the electrophysiological techniques that can be employed to isolate and record specific membrane
Evaluating Amyloid Beta (A) 1-40 Degradation by Capillary Electrophoresis
Here, we describe a capillary electrophoresis method for evaluating proteolysis of the amyloid beta peptide (Aβ) 1–40. This method is suitable for kinetic studies, demands little specialized equipment, and consumes only small
A detailed understanding of the biochemical events leading to the proteolytic excision of the β-amyloid peptide (A β) from the amyloid precursor protein (APP) has eluded many researchers. This is largely because the measurement of the various APP
