RNA |

|
| Source name |
SIRT1 old
|
| Organism |
Mus musculus |
| Characteristics |
age: old
genotype: SIRT1F/F
cell type: microglia
genetic background: BL6 and 129/Sv
|
| Treatment protocol |
Adult microglia were isolated from SIRT1F/F or LysM-Cre/SIRT1F/F mice as described with some modifications. Brains were placed in a culture dish with enzyme solution and the digested brains were triturated with a 20-ml pipette and passed through 70-μm filter. After centrifugation, cells were incubated with anti-myelin microbeads, centrifuged, resuspendend and washed. Myelin-negative fractions were collected and further processed by incubating with anti-CD11b microbeads at 4°C for 15 min. After washing, the resuspended myelin negative fraction was passed through an autoMACS Pro Separator, and then the CD11b-positive population was separated from CD11b-negative population. Cells were centrifuged, and the pellets were lysed with RNA lysis buffer (QIAGEN) for microarray or quantitative RT-PCR.
