Title |
HEK293T-RBFOX2- STAMP 48h low rep2 |
Sample type |
SRA |
|
|
Source name |
HEK293T
|
Organism |
Homo sapiens |
Characteristics |
cell line: HEK293T
|
Treatment protocol |
For STAMP fusion protein expression STAMP stable HEK293T cells were induced with 50ng/ml (low) or 1ug/ml (high) doxycycline in DMEM for 24-72 hours, followed by Trizol extraction and Direct-zol miniprep (Zymo Research) column purification in accordance with manufacturer protocol. Uninduced cells of the same genetic background were used as negative controls. For mTOR perturbation experiments, cells were treated with 100nM Torin-1 or 100nM insulin alongside 1ug/ml doxycycline induction and harvested for RNA after 72 hours 37C incubation.
|
Growth protocol |
All stable STAMP HEK293T cell lines were generated using human lenti-X HEK293T cells (HEK293XT, Takara Bio) which are derived from transformed female human embryonic kidney tissue. Cells were maintained in DMEM (4.5 g/L D-glucose) supplemented with 10% FBS (Gibco) at 37o C with 5% CO2. Cells were periodically passaged once at 70-90% confluency by dissociating with TrypLE Express Enzyme (Gibco) at a ratio of 1:10.
