β amyloid (11 22)

β-amyloid 1-11 acetate(190436-05-6 free base) 是 Amyloid-β 肽的片段，可用于神经系统疾病的研究。

β-Amyloid (11-22) is a peptide fragment of β-Amyloid. Beta-amyloid peptide (Abeta), the primary component of amyloid plaques in the brains of Alzheimer’s patients, is believed to be the cause of Alzheimer’s Disease (AD), the most common neurodegenerative disorder.

β-Amyloid (22-35) is a 14-aa peptide, shows aggregates and induces neurotoxicity in the hippocampal cells. Beta amyloid (22-35) is a synthetic truncated fragment of beta-amyloid peptide.

(Pyr11)-Amyloid β-Protein (11-40) (A beta 11pE-40) 作为一种肽， 主要应用于阿尔茨海默病相关研究。

β-Amyloid 22-35 (Amyloid β-Protein 22-35) TFA是β-淀粉样蛋白22-35残基段，具细胞毒性，能影响无血清培养大鼠海马神经元。在中性缓冲液中，此化合物能形成聚集体与典型淀粉样纤维，模拟β-淀粉样蛋白行为。

Anionic interaction of Beta-amyloid (1-11) with Factor XII is suspected to cause massive activation of the C4 (complement 4) system in the cerebrospinal fluid of Alzheimer’s disease patients.

This synthetic peptide consists of amino acids 22 to 40 of beta amyloid protein. This peptide sequence is often used in beta amyloid structure and aggregation studies.
