Sample GSM1924609 Query DataSets for GSM1924609
Status Public on Dec 31, 2016
Title 165_NS
Sample type SRA
 
Source name rectal tissue_negative for E. coli O157
Organism Bos taurus
Characteristics tissue: rectum
phenotype: negative for E. coli O157
Treatment protocol Cattle with two phenotypes, control group was cattle negative for E. coli O157, experimental group was cattle shedding > 10^4 CFU E. coli O157/g of feces
Extracted molecule total RNA
Extraction protocol Two 2 cm^2 biopsies 3-5 cm proximal to the rectal-anal junction were collected from each animal and immediately flash frozen in liquid nitrogen within 10 min after death of the animal. Samples were stored at -80 °C until RNA was extracted. 100 mg of powdered rectal tissue was used for RNA extraction using a mirVana total RNA Isolation Kit
Illumina TruSeq Small RNA Sample Preparation kit
 
Library strategy miRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina HiSeq 2000
