| Title |
Homozygous Stage5 Rep2 |
| Sample type |
SRA |
| |
|
| Source name |
Whole embryo
|
| Organism |
Drosophila melanogaster |
| Characteristics |
developmental stage: Cellular blastoderm
genotype: zen[7] homozygous
embryonic stage: stage 5
|
| Treatment protocol |
zen[7] homozygous embryos were selected using a genotyping procedure described by Ghanim and White (2006). In our case, both the absence of lacZ specific band together with the presence of a control band (non-coding region of gene Dtg) were indicators of homozygous lethal embryos.

| Extracted molecule |
total RNA |
| Extraction protocol |
For RNA extractions, extracts of homozygous (zen[7]) and heterozygous (zen[7]/TM3, ftz-lacZ) staged embryos, previously preserved in RNAWIZ reagent (N = 100) were pooled, then samples were carefully homogenized in a 1.5 mL Eppendorf tube on ice with the aid of RNAse-free polypropylene pellet pestle. After homogenization, RNA extraction was performed using standard protocols. RNA was quantified using Qubit RNA HS Assay Kit (Thermo Fisher) and the integrity was assayed in a Tape station 2200 (Agilent Technologies). Samples were treated with Turbo DNA-free DNase (Ambion) to remove contaminating DNA.
Transcriptome sequencing was performed at the Duke Center for Genomic and Computational Biology in a Hiseq2000 platform (Illumina) with a 100 bp pair end library and 200 bp insert size
