| Title |
Primary ovine microglia PrPSc bio repB tech rep2 (Inoc12B.2.2) |
| Sample type |
RNA |
| |
|
| Source name |
primary ovine microglial cells inoculated with PrPSc
|
| Organism |
Ovis aries |
| Characteristics |
Primary ovine microglia
|
| Treatment protocol |
Primary microglia were passed into 6-well plates and grown to approximately 60% confluency. Microglia were rinsed once with PBS and then overlaid with 200 μl of a 1/20 dilution of either the Rov9Sc lysate (Inoc A, B, and C) or the Rov9C lysate (Mock A, B, and C) in OPTI-MEM. All replicates (A, B, and C) of both treatment groups (Inoc and Mock) were incubated for six hours and then 200 μl of OMEM were added to each well. Following an additional two days of incubation, 0.5 ml of OMEM was added to each well, and microglia were incubated for four days at which time they were expanded into 25-cm2 tissue culture flasks. Microglia were fed every three to four days with OMEM as necessary and serially passed 1/5 after reaching confluence.
|
| Growth protocol |
Microglial cells were cultured using standard techniques, in OPTI-MEM I Reduced Serum Medium (Invitrogen, Carlsbad, CA) supplemented with 10% heat-inactivated FBS, 2 mM L-glutamine, 10 IU/ml of penicillin, and 10 mg/ml of streptomycin.

| Description |
PrPSc infected primary ovine microglial cells
|
| Data processing |
All analyses of microarray data were conducted using Bioconductor for R (www.R-project.org). Data were normalized using the Micro Array Suite 5.0 (MAS5) algorithm. The ComBat algorithm (http://statistics.byu.edu/johnson/ComBat/) was used to correct for batch effect.
