Amyloid β-peptide (1-40) (rat) is the prone-to-aggregation product of amyloid precursor protein proteolytic cleavage, and is the major constituent of senile plaques observed in the brain of Alzheimer's disease. The Amyloid β-peptide (1-40) (rat)-treated rats require longer to find the platform hidden under the water. In the visible platform test, the latency for each group is similar (20.56±11.31 s in control and 14.68±9.97 s in Amyloid β-peptide (1-40) (rat) group, p=0.304). Among these tested proteins, 6 ones are significantly up-regulated and 7 ones significantly down-regulated in Amyloid β-peptide (1-40) (rat) group comparing with the control. Tubulin β chain is significantly down-regulated in Amyloid β-peptide (1-40) (rat) group (p=0.014) when compare with control. Similar changes are also observed for ATP synthase β subunit (p=0.010) and synapsin Ib between Amyloid β-peptide (1-40) (rat) and control groups, but not significantly for synapsin Ib (p=0.295)[1].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
