Sample GSM953480 Query DataSets for GSM953480
Status Public on Sep 01, 2013
Title 10 day old heads spermidine food 1
Sample type SRA
 
Source name Drosophila heads
Organism Drosophila melanogaster
Characteristics food: standard Drosophila media with 5mM spermidine
age: 10 days after eclosion
tissue: heads
Treatment protocol /flies were cultured either in the presence or absence of 5mM spermidine
Growth protocol Flies were cultures according to standard methods at 25 degrees with a 12 hour light dark cycle
Extracted molecule total RNA
Extraction protocol Spd- and Spd+ flies were frozen in liquid nitrogen and heads were collected after vortexing by mechanical separation. Poly A+ RNA was extracted from approximately 50 ul of heads per sample using the RNeasy Lipid tissue Mini kit (Qiagen) and the Oligotex mRNA mini kit (Quiagen). RNA was reverse transcribed into a cDNA using the Superscript III Reverse Transcriptase Kit (Invitrogen) for first strand synthesis. Second strand synthesis was performed with E.coli and T4 DNA polymerases (New England Biolabs). DNA end repair was performed on 9-20 ng of cDNA followed by ligation of adaptors, and size selection for 300 bp fragments using the E-gel Size Select gel (Invitrogen). Fragments were amplified using 14 PCR cycles and linear amplification was validated by qPCR.
