Sample GSM172531 Query DataSets for GSM172531
Status Public on Mar 02, 2007
Title Microarray profile of Cervical Cancer Cell Line- SiHa
Sample type RNA
 
Channel 1
Source name Cervical Cancer Cell Line
Organism Homo sapiens
Characteristics This line was established from fragments of a primary tissue sample obtained after surgery from a Japanese patient. Electron microscopic observations revealed presence of typical desmosomes at the cell junctions and an abundance of tonofilaments in the cytoplasm.
The line is reported to contain an integrated human papillomavirus type 16 genome (HPV-16, 1 to 2 copies per cell). {Information obtained from: http://www.atcc.org/common/catalog/numSearch/numResults.cfm )
Biomaterial provider Dr. Sudhir Krishna, National center for Biological Sciences, Bangalore, India
Treatment protocol No treatment, Grown in prescribed media till subconfluent.
Growth protocol Dulbecco's Minimum essential medium with 10%
fetal bovine serum, Temperature: 37.0C
Extracted molecule total RNA
Extraction protocol TriZol Extraction protocol with an additional chloroform extraction step followed by quantitation in spectrophotometer and checking on formaldehyde-agarose gel. RNA stored in 10mM Sodium Citrate Buffer (Ambion).
Label Cy5
Label protocol Amino-allyl dUTP based indirect labelling protocol described by Pat Brown Lab, available at http://cmgm.stanford.edu/pbrown/protocols/index.html
 
Channel 2
Source name Human Universal Reference RNA
Organism Homo sapiens
Characteristics Purchased from (Stratagene, Cat No. 740000),the Human Universal Reference RNA comprises of a pool of RNA made from 10 different human cell lines including: Adenocarcinoma, mammary gland Melanoma, Hepatoblastoma, liver Liposarcoma Adenocarcinoma, cervix Histiocytic lymphoma; macrophage; histocyte, Embryonal carcinoma, testis Lymphoblastic leukemia, T lymphoblast, Glioblastoma, brain, Plasmacytoma; myeloma; B lymphocyte
Biomaterial provider Stratagene, Cat No. 740000

Label Cy3
Label protocol Amino-allyl dUTP based indirect labelling protocol described by Pat Brown Lab, available at http://cmgm.stanford.edu/pbrown/protocols/index.html
 
 
Hybridization protocol Hybridization in 2XHyb buffer containing 50%formamide, 10X SSC and 0.2%SDS (adapted from Quackenbush protocol) in a 42 degrees Centigrade waterbath overnight in a Hyb chamber, with the probe under a coverslip, as described by Pat Brown Lab http://cmgm.stanford.edu/pbrown/protocols/index.html
Scan protocol Scanned in Axon 4200A Professional according to the manufacturer's instructions.
Description none
Data processing Slides have been scanned by Axon scanner 4200A and data analyzed by GenePix Version 5.0. 'Value' column represents normalized, log transformed, ratio of medians of CH1/CH2. Normalization has been carried out with respect to 'all normalization features' using GenePix software. Normalization features meet the following criteria:[F532 Median]>= 250 And [F635 Median]>= 250 And [F Pixels]>=30 And [Dia.]>=50 And[% >B635+1SD]>55 And[% >B532+1SD]>55
