Sample GSM533939 Query DataSets for GSM533939
Status Public on May 24, 2010
Title renal allograft biopsy, (U of A/Chicago) 126A4AGX7
Sample type RNA
Source name renal allograft biopsy
Organism Homo sapiens
Characteristics failed=1/non failed=0: 0
time of biopsy post transplant (days): 42
time from biopsy to failure/censoring (days): 1167
rejection/non rejection: nonrej
sample included in the main analysis- the first biopsy per patient from the 105 late (> 1 year) patients: 0
Treatment protocol The immunosuppressive treatment of the patients before the biopsy was based on individual treatment regiments; the treatment after the biopsy was adjusted based on the histopathological diagnosis.
Growth protocol All human renal allograft biopsies taken for clinical indication during the period specified above were included. Tissue was immediately placed in RNA later.
Extracted molecule total RNA
Extraction protocol Following homogenization of the tissue in 0.5ml of Trizol reagent (Invitrogen, Carlsbad, CA), total RNA was extracted and purified using the Rneasy Micro Kit (Quiagen, Ontario, Canada) (average yield 4ug/core, (RNA integrity number >7).
Label biotin
Label protocol RNA (1-2ug) was labeled using GeneChip HT One-Cycle Target Labeling and Control kit. Quality of labeled cRNA was assessed on an Agilent 2100 Bioanalyzer (Agilent, Palo Alto, CA) before hybridization to HGU133Plus2.0. GeneChip (Affymetrix, Santa Clara, CA).
Hybridization protocol Following fragmentation, 15 ug of cRNA were hybridized for 16 hr at 45C on GeneChip HGU133 Plus 2.0 Human Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
Scan protocol GeneChips were scanned using Gene Array Scanner (Affymetrix) and processed with GeneChip Operating Software Version 1.4.0 (Affynetrix).
Description Samples with the same initial numbers in the sample names are replicates from the same patient. For the main analysis, only the earliest biopsy per patient was used, and only in those patients with a biopsy taken > 1 year post-transplant
Data processing Microarray data files were preprocessed using robust multi-chip averaging (RMA) implemented in Bioconductor.
