TGFB1 stimulated A375 Smad2/3 6.11.18 |
| Sample type |
SRA |
| |
|
| Source name |
A375 Cells
|
| Organism |
Homo sapiens |
| Characteristics |
chip antibody: Smad2/3
cell line: A375 Cells
treatment: TGFB1
|
| Treatment protocol |
Cells were starved for 2 hours. Treated with 10ng/mL TGFB1 ligand or 4mM HCl containing 1mg/mL BSA vehicle control for 2 hours.
|
| Growth protocol |
A375s were grown in filter sterilized DMEM, 10% FBS, 1% PenStrep, 1% Glutamine at 37°C
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
A375 cells were fixed directly in 15cm plates with 11% formaldehyde and collected by scraping. Approximately 100,000,000 cells were used per condition. Cells were lysed using lysis buffers with protease inhibitors (Roche #05056489001) and sonicated such that fragmented chromatin was 200-300bp long. Optimal chromatin length was confirmed by gel electrophoresis. Prior to antibody addition, 50µL chromatin was collected for input sample. The remaining sonicated chromatin was incubated overnight at 4°C with 10µg antibody attached to Dynabeads (Invitrogen #10004D). Samples (including inputs) were washed with wash buffers and eluted for 6 hours at 70°C, treated with RNaseA (Sigma #R4642) and ProteinaseK (Life Technologies #AM2546), and purified using Zymo ChIP DNA Concentrator kit (Genesee Scientific #11-379C).
Libraries were end repaired (VWR #ER81050), polyA tailed (Invitrogen #18252-015, NEB #M0212L), adaptor ligated (NEB #E7335), size selected using Ampure XP beads (Beckman Coulter #A63881, Life Technologies #12027), and PCR amplified (NEB #M0531).
