Sample type |
SRA |
|
|
Source name |
Pol II IP DNA from gd7 embryos expressing the transgene twiBAC-Yellow
|
Organism |
Drosophila melanogaster |
Characteristics |
tissue: whole gd7 embryos tissue type: dorsal ectoderm genotype: maternally gd7/gd7 mutants and zygotically expressing the transgene twiBAC-Yellow chip antibody: Pol II (4H8, Millipore)
|
Treatment protocol |
no treatment, only fixation of embryos in formaldehyde
|
Growth protocol |
D. melanogaster embryos were collected and aged on yeasted apple juice plates at 25 °C and 60 % humidity.
|
Extracted molecule |
genomic DNA |
Extraction protocol |
ChIP-seq: DNA-protein-complexes were isolated with specific antibodies. Sequencing libraries were prepared following Illumina's instructions: DNA was end repaired using T4 DNA polymerase, DNA polymerase I large fragment (Klenow polymerase) and T4 polynucleotide kinase. A single 3'-A overhang was added to the blunted ends using Klenow 3'-5' exo- polymerase. Adapters with single 3'-T overhangs were ligated to the adenylated fragments, and after a size-selection step on a 2 % agarose gel (150-250 bp) the adapter modified DNA was PCR-amplified. Following cluster generation on the flowcell surface, the sequencing libraries were sequenced following Illumina's protocol.

Description |
Pol II IP DNA from gd7 embryos with one copy of a 25kb TwistBAC where the twi coding region has been replaced by the yellow sequence
|
Data processing |
Reads were aligned to the UCSC dm3 genome with the addition of specific BAC sequences as pseudo-chromosomes with bowtie v0.12.7. Only uniquely aligning reads with up to two mismatches were retained. For paired-end samples, successfully aligned mate pairs were joined to a single fragment. Genome Build: gd_pol.bed: dm3
