| | Cellular Assay of Aβ Production |
| Description: | Test Example 3: The potency of compounds against BACE1 activity was determined in a cellular assay of Aβ production. Human SK-N-BE(2) neuroblastoma cells (ATCC No. CRL-2271) were plated at 96,000 cells/well/100 uL in 96-well plates in RPMI1640 medium/10% fetal bovine serum (FBS)/penicillin-streptomycin and cultured for 24 hours at 37° C., 5% CO2. Test compounds were dissolved in dimethyl sulfoxide and diluted with dimethyl sulfoxide and put into RPMI1640/5% FBS/penicillin-streptomycin media (final dimethyl sulfoxide concentration is 0.5%). The culture media in 96-well plates were replaced by 125 uL/well of the media containing test compounds. After incubation for 6 hours at 37° C., 5% CO2, 30 uL of the media were transferred into a fresh 96-well plate and used for Aβ40 assay by an enzyme-linked immunosorbent assay (ELISA) kit (#27718, Immuno-Biological Laboratories, Japan) according to the manufacturer's protocol. Cell viability was measured by CellTiter-Glo Luminescent Cell Viability Assay (#7571, Promega) after removal of 30 uL of the media for the Aβ assay. |
