Sample GSM219878 Query DataSets for GSM219878
Status Public on Oct 09, 2007
Title HCC1806
Sample type RNA
 
Source name University of Cambridge
Organism Homo sapiens
Characteristics Plate = 1
Extracted molecule total RNA
Extraction protocol Standard Trizol extraction protocol, modified by washing the final RNA pellet with 80% EtOH
Label Biotin
Label protocol Indirect PCR-based labelling method: Linkers were ligated to the 3' and 5' end of miRNAs, cDNA was synthesized using superscript Reverse Transcriptase, cDNA was labelled (Biotin) and amplified by PCR
 
Hybridization protocol 15ul sample and 33ul of the bead pool were incubated overnight at 50ÂșC and washed after 16 hours
Scan protocol Median fluorescence intensity values were measured on a Luminex 100 machine
Description Breast cancer cell line
Data processing Raw values smaller than 1 were set equal to 1. After log2 transformation probes were filtered by requiring each probe to exceed 6 in at least one sample. Systematic probe effects between plates were removed by subtracting differences between the probe median for the samples on a given plate and the probe median for all samples on both plates. Unused probes were removed and replicate probes were summarized by their mean expression profile. Two alternative between-sample normalizations were used: 1) Median centering (VALUE) The sample median was subtracted for each sample. Replicate samples were summarized by their mean expression profile. 2) Control-based normalization (CTRL_BASED_NORM) Control probes used for normalization as indicated in 'USAGE' were median centred. Sample effects were estimated by taking the mean over eight control measurements per sample. Normalization was performed by subtracting the estimated effect for each sample. Replicate samples were summarized by their mean expression profile.

ID_REF
RAW1 Raw data, median fluorescence intensity reading
VALUE Preprocessed data using sample median centering (NULL corresponds to absent or replicate probes; in the case of replicate probes only one probe was assigned the summarized expression value for the relevant miRNA)
CTRL_BASED_NORM Preprocessed data using control-based sample normalization (NULL corresponds to absent or replicate probes; in the case of replicate probes only one probe was assigned the summarized expression value for the relevant miRNA)
