2_4_mat: Small RNAs from ovaries of 2.4 mat transgenic strain |
Sample type |
SRA |
|
|
Source name |
ovaries
|
Organism |
Drosophila melanogaster |
Characteristics |
tissue: ovaries strain: 2.4 mat molecule subtype: small RNAs
|

Extracted molecule |
total RNA |
Extraction protocol |
smallRNA-seq: Total RNA was isolated by Trizol (Invitrogene) and size-fractioned by PAGE (19-29 nt). smallRNA-seq: Libraries of small RNAs 19-29 nt were constructed as previously described in (Muerdter et al. 2012) GRO-seq: Nuclei were purified from homogenized ovaries, and were used for run-on reacton with Br-UTP in vitro (Rozkov et al. 2013). GRO-seq: De novo synthesized RNA was subjected to library preparation for RNA-seq.

Data processing |
smallRNA-seq: Reads with clipped 3'-adapter (5'-TGGAATTCTCGGGTGCCAAGG) were passed through length (>18 nt), quality (80% of nt should contain >=20 Phred score) and artefacts filters, and mapped by bowtie2 to dm3 genome assembly and transgene sequences. GRO-seq: Reads were clipped 3'-adapter (5'-TGGAATTCTCGGGTGCCAAGG), reads smaller than 19 nt were discarded. Reads were mapped to the dm3/R5 genomic assembly of transgene sequence by bowtie2 and deduplexed. Only single-mapped reads were used for the construction the genomic profiles. Genome_build: dm3 Supplementary_files_format_and_content: smallRNA-seq: Tab-delimited file include the raw counts of clipped read occurrences. GRO-seq: Genomic profiles of RPM-normalized single-mapped reads.
