Teves 11, Genome wide nucleosome and Pol-II maps in S2 cells after HS treatment.


Intact nuclei of D. melanogaster S2 cells were extracted and processed to isolate "active" chromatin (low salt concentration: 80mM), "inactive" chromatin (high salt concentration: 350mM) and total chromatin.

Several treatments were aplied to the cells:

Several techniques were used:

Technical Notes

Paired-end sequencing was done on all samples. Raw data was presented an SAM files and BED files (only for 3 samples names Total with treatment). The SAM files were converted to BED using SAMtools and BEDtools. Resulting BED files contained only plus strand tags without information on the paired tag. Final conversion to SGA files was done using ChIP-Seq with unstranded output (-u option).
