| 一般建议 | 为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异，仅做参考。若实验所需浓度过大至产品溶解极限，请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存，请尽快用完。 |
在阿尔茨海默病（AD）中，β-淀粉样蛋白(Aβ）可以引发神经退行性病变 1。在非正常生理条件下，由β淀粉样前体蛋白(β-amyloid precursor protein,APP)水解产生，是一种分解代谢副产物2。
Aβ是许多不同受体和其它分子的配体3-5，通过复杂转运通路在组织和血脑屏障中运输。Aβ响应于各种不同的环境压力，能够诱导促炎活性7。
可溶性β淀粉样多肽片段是明胶酶A/ IV型胶原酶/MMP-2及APP分泌酶的底物，作用于Lys16和Leu17之间，使蛋白断裂。
