一般描述

β-淀粉样蛋白前体蛋白 (APP) 是由蛋白水解酶β-分泌酶 (BACE1) 和 γ-分泌酶依次裂解，生成以Aβ1-42和 Aβ1-40型为主的β-淀粉样蛋白 (Aβ) 肽。分泌的Aβ肽通过再吸收机制和之后的内体降解过程降解，或通过胞外胰岛素降解酶降解。Aβ的胞外积累导致聚集体和原纤维的形成，最终形成淀粉样蛋白沉着物神经炎斑，其是阿尔茨海默病 (AD) 的标志物。
淀粉样β-肽（Aβ), 一种 含38至 43 个氨基酸的肽，来源于β-淀粉样前体蛋白（APP）。β-淀粉样蛋白基因位于人染色体21q21上。APP是一种I型跨膜蛋白。它在内质网（ER）中产生，然后在高尔基体的协助下迁移至反面高尔基网（trans-Golgi-network，TGN）。
该抗体可识别人 β-淀粉样肽、全长淀粉样前体蛋白 (APP)、可溶性 APP（sAPPβ′和 sAPPα）、C99 裂解 形式和 Aβ(1-40/42)，但不是可溶性 APP 形式 sAPPβ。

免疫原

相当于人 β1-11 氨基酸的合成肽——淀粉样蛋白。

应用

单克隆抗 β-淀粉样蛋白抗体已用于 IgG1 和 IgG2a 同种型抗体的滴定。它也被用于合成抗体功能化的磁性纳米颗粒。
小鼠单克隆抗-β-淀粉样蛋白抗体已可用于蛋白质印迹分析。本品还可用于免疫组织化学、免疫沉淀、间接ELISA和微阵列研究。
此抗体已成功使用的应用，以及相关的同行评审论文如下。

生化/生理作用

β-淀粉样蛋白基因是胰岛素降解酶（IDE）的底物。它在阿尔茨海默病（AD）和2型糖尿病（DM2）的发病机制中发挥主要作用。

目标描述

淀粉样蛋白是由错误折叠的蛋白质和多肽组成的不溶性蛋白聚集体。淀粉样蛋白沉积与多种神经退行性疾病有关。

外形

0.01M 磷酸缓冲盐溶液，pH 7.4，含 15mM 叠氮化钠。
