| Title |
Drosophila simulans embryo small RNA [M025_dsim_embryo] |
| Sample type |
SRA |
| |
|
| Source name |
D. simulans embryo small RNA
|
| Organism |
Drosophila simulans |
| Characteristics |
tissue: whole embryo
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Male and female bodies were isolated in bulk using sieves after sorting by sex. Animals were flash frozen in liquid nitrogen followed by vortexing. This procedure severs heads from the thorax and abdomen allowing separation of these two body parts when sifted through chilled fine mesh sieves. Here we used a .600mm sieve to collect male bodies. Total RNA was then extracted from the bodies using TRIzol according to manufacturer protocol.
For Illumina GAII Libraries: From total RNA, ~18-26 nt fraction was isolated using PAGE and cloned using ligation to adapters requiring 5' monophosphate and 3' OH.
For Illumina HiSeq Library: Libraries were created with the Illumina truseq small RNA cloning kit using a modified protocol. Small RNAs in the 18-29nt size range were first isolated from total RNA by PAGE purification before cloning. PAGE purification was also performed after ligation of RNAs to 3’ and 5’ linkers before processing in subsequent steps. All enzymatic reactions and oligos were used as indicated by manufacturer.
