|
|
Source name |
CUT&Tag
|
Organism |
Drosophila melanogaster |
Characteristics |
antibody: Anti-Rpb3 Bethyl Laboratories Catalog # A303-771A cell type: :Kc167 Drosophila melanogaster cell line originally derived from disaggregated 8-12 hour embryos.
|
Extracted molecule |
genomic DNA |
Extraction protocol |
https://www.protocols.io/view/cut-amp-tag-direct-with-cutac-x54v9mkmzg3e/v8 CUT&Tag uses tagmentation in which the barcoded adapters are integrated on both sides of the insert, so that the DNA that is released is already a barcoded library. PMID:31036827

Description |
CUT&Tag data profiling Total RNA pol II (Rpb3 subunit) in Drosophila melanogaster cells treated with aclarubicin for 30 minutes
|
Data processing |
Genome_build: dm6 1. We used cutadapt 2.9 with parameters "-j 8 --nextseq-trim 20 -m 20 -a AGATCGGAAGAGCACACGTCTGAACTCCAGTCA -A AGATCGGAAGAGCGTCGTGTAGGGAAAGAGTGT -Z" to trim adapters from 50bp paired-end reads. 2. We used Bowtie2 2.4.2 with options "--very-sensitive-local --soft-clipped-unmapped-tlen --dovetail --no-mixed --no-discordant -q --phred33 -I 10 -X 1000" to map the paired-end 50bp reads to the dm6 Drosophila melanogaster reference sequence obtained from UCSC. 3. We used Bowtie2 2.4.2 with options "--end-to-end --very-sensitive --no-overlap --no-dovetail --no-mixed --no-discordant -q --phred33 -I 10 -X 1000" to map the same paired-end 50bp reads to the masked hg19 Homo sapiens reference sequence obtained from UCSC. 4. We extracted properly paired reads from the D. melanogaster alignments. 5. We counted the properly paired reads from the Homo sapiens alignments. 6. We used bedtools 2.30.0 genomecov to make a normalized count dm6 track which is the fraction of counts at each base pair scaled by the size of the dm6 reference sequence (137567484) so that if the counts were uniformly distributed across the reference sequence there would be one at each position (Supplementary file .norm.bw) 7. We used bedtools 2.30.0 genomecov with a scaling factor of (10000/number of fragments mapped to masked hg19) to create a calibrated dm6 track file (Supplementary file .Hs_spike.bw).
