| Title |
U2OS, pLVX-NAB2-STAT6, 2 days doxycycline, FLAG, biol rep1 |
| Sample type |
SRA |
| |
|
| Source name |
U2OS
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: U2OS
cell type: osteosarcoma
genotype: pLVX-NAB2-STAT6
treatment: 2 days 1ug/mL doxycycline
chip antibody: M2-Flag (Sigma-Aldrich F1804)
|
| Treatment protocol |
Lentiviruses were produced in HEK293T cells by co-transfection 8 ug of pLVX-Tet-On Advanced (ClonTech) and pLVX-NAB2-STAT6-FLAG-Tight-Puro. U2OS were passaged into a 6-well plate at 30-40 % confluence. When the cells reached 60-70% confluence, 2 ml of virus medium per well (cell medium with 4 ul of lentiviral particles per ml and 8 ug/ml polybrene (Thermo Fisher, cat#TR1003G)) was added to replace old medium. 24 hours after induction, the virus medium was removed and replaced with fresh cell culture medium for another 48 hours. After that, cells were selected with 200 ug/ml of Neomycin (Corning, cat#MT30234CR) in fresh medium. Cells were selected in Neomycin for two weeks with fresh media being added 3-4 weeks and cells split 1:3 when reaching 80-90% confluency. Then cells were plated into a 6-well plate at 30-40 % confluence. When the cells reached 60-70% confluence, 2 ml of medium fresh lentivirus media generated using pLVX-NAB2-STAT6-FLAG-Tight-Puro with 8 ug/ml polybrene (Thermo Fisher, cat#TR1003G) per well was added to replace the old medium. 24 hours after induction, the virus medium was removed and replaced with fresh cell culture medium for another 48 hours. After that, cells were selected with 0.5 ug/ml of puromycin in fresh medium (InvivoGen, cat#ant-pr-1). 48 hours after selection with puromycin, cells were disassociated with Trypsin and plated at a low density in a 15 cm dish. Single cells were cultured with 0.5 ug/ml of puromycin for the next 2-3 weeks until colonies appeared. Individual microcolonies were moved to a 96-well plate for clonal expansion. Clones were screened after addition of 1ug/mL Doxycline by verified by Western Blot. ChIP-seq was done without doxycycline treatment and after 2 days of 1ug/mL doxycycline treatment.
