| Treatment protocol |
80% confluant cells were stimulated with 10ng/ml recombinant TGFβ1 for 1 hour prior to formaldehyde crosslinking.
|
| Growth protocol |
cells grown in RPMI 1640 supplemented with 10% FBS in 5% CO2 incubator at 37C. Cells were inspected daily and split at ~70% confluance.

| Extraction protocol |
Lysates were clarified from sonicated nuclei and SMAD4-DNA complexes were isolated with antibody. Libraries were prepared according to Illumina's instructions accompanying the ChIP-seq DNA Sample prep Kit (Part# IP-102-1001). Briefly, DNA was end-repaired using a combination of T4 DNA polymerase, E. coli DNA Pol I large fragment (Klenow polymerase) and T4 polynucleotide kinase. The blunt, phosphorylated ends were treated with Klenow fragment (32 to 52 exo minus) and dATP to yield a protruding 3- 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3’ end. After adapter ligation DNA was PCR amplified with Illumina primers for 12 cycles and library fragments of ~250 bp (insert plus adaptor and PCR primer sequences) were isolated from a 2% E-gel from invitrogen. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer following the manufacturer's protocols.
