In Vitro	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].
Cell Assay	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].
