Sample GSM213067 Query DataSets for GSM213067
Status Public on Jul 16, 2008
Title Crypt LCM LOI(+) rep3
Sample type RNA
 
Channel 1
Source name Crypt_LCM_LOI(+)
Organism Mus musculus
Characteristics Strain: C57BL/6
Gender: male
Age: 120 days
Development stage: adult
Individual Identifier: LOI(+)3 251279910119
Biomaterial provider Dr. Andrew Feinberg
Treatment protocol The mouse was euthanized by CO2 inhalation and the small intestine was collected and washed with PBS. Pieces of the middle part of the small intestine were collected and frozen at -80C, embedded in OCT, sectioned at 10um, and fixed with 70% EtOH on the slides. Slides were stained with hematoxylin, dehydraded and used for LCM within one week. 5,000 to 13,000 intestinal crypts were dissected by LCM, and RNA was extracted using RNeasy (QIAGEN).
Extracted molecule total RNA
Extraction protocol Total RNA extracted from microdissected crypts using RNeasy as directed by manufacturer. Samples QCs on an Agilent Bioanalyzer for RNA quality and quantity.
Label Cy3
Label protocol Total RNA was labeled using Agilents Fluorescent Linear Amplification kit, according to manufacturers instructions (Product Number G2554A or P/N G2556-66002, Version 3.0, June 2002).
 
Channel 2
Source name Universal Mouse Reference RNA
Organism Mus musculus
Characteristics Universale Mouse Reference
Growth protocol The UMRR is provided in a solution of 70% ethanol and 0.1 M sodium acetate. Prepare the UMRR for use as follows: 1.Centrifuge the tube at 12,000 x g for 15 minutes at 4C. 2.Carefully remove the supernatant. 3.Wash the pellet in 70% ethanol. 4.Centrifuge the tube at 12,000 x g for 15 minutes at 4C. 5.Carefully remove the supernatant and air-dry the pellet at room temperature for 30 minutes to remove retained ethanol. 6.Resuspend the pellet in RNase-free water to the desired concentration.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from cultured cells using a Stratagene Absolutely RNA kit. DNase-treated total RNA samples from 11 cultured cell lines derived from embryo, embryo fibroblast, kidney, liver/hepatocyte, lung/alveolar macrophage, B-lymphocyte, T-lymphocyte (thymus), mammary gland, muscle myoblast, skin, and testis were pooled in equal parts
Label Cy5
Label protocol Total RNA was labeled using Agilents Fluorescent Linear Amplification kit, according to manufacturers instructions (Product Number G2554A or P/N G2556-66002, Version 3.0, June 2002).
 
 
Hybridization protocol Agilent 60-mer oligo microarray processing protocol (SSC Wash/SureHyb Chamber set-up) V4.1, April 2004. Agilent Publication Number: G4140-90030 V4.1 APRIL 2004.
Scan protocol Slides were scanned with an Agilent DNA Microarray Scanner model G2505-64120 at 100% PMT in both channels, with a scan resolution of 10um. A scan window of 61 x 21.6 mm was used, then images were cropped to size and saved in a modified two-color TIFF format. Images were examined visually for evidence of foreign debris or major failures.

Data table header descriptions
ID_REF Feature Number (FeatureNum). Please check the platform file for the annotation.
VALUE The normalized VALUE among all the arrays in the series. It is caculated with the following method: (1) Take values from the columns gDyeNormSignal,rDyeNormSignal in the raw files and log-transform them using: log10(max(x,1)). These values will be referenced below as Xgi and Xri where i is array number. (2) Take average of Xri's for the oligo among 6 arrays in the series: AverXr = average(Xri). (3) For each array estimate Yi = Xgi-Xri+AverXr (4) Round Yi to 4 decimal digits. This is used as the normalized VALUE. More detailed information with error correction can be found at http://lgsun.grc.nia.nih.gov/ANOVA/help.html#arrayjoin
