Protocol

Cell experiment:

After treating the hippocampal slices with 20 μM β-Amyloid (1-42) for 4 h, supernatant is replaced by fresh H-ASCF/3 (0.9 mL/chamber) to which 0.1 mL MTT stock solution (5 mg/mL H-ACSF/3) is added (MTT final concentration: 0.5 mg/mL). The chamber is left to rest for 15 min without carboxygenation. To stop further reduction of MTT, the medium (H-ACSF/3) is removed. The slices are transferred into 96-well plate, then pure DMSO (100 μL/slice/well) is added for dissolving formazane from the slices. (30 min in a 96-well plate). Then 70 μL DMSO solution from each slice (well) is transferred into another 96-well plate. The optical density (OD) of the dissolved formazane is measured at 550 and 620 nm[1].

Background

β-Amyloid (1-42), rat is a 42-aa peptide, shows cytotoxic effect on acute hippocampal slices, and used in the research of Alzheimer's disease. Amyloid-β[1]

β-Amyloid (1-42), rat shows cytotoxic effect on the hippocampal slices at 20 μM[1]. β-Amyloid (1-42), rat causes morphological changes in NGF-induced PC12 cells, induces formed cell processes to retract in differentiated cells and affect the expression of exons 2/3 in both undifferentiated and differentiated cells[2].

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
