Sample GSM987868 Query DataSets for GSM987868
Status Public on Aug 28, 2012
Title C. tropicalis Opaque Block 7
Sample type RNA
 
Channel 1
Source name C. tropicalis opaque cells
Organism Candida tropicalis
Characteristics strain: CAY2275
colony and cellular morphology: opaque state
Biomaterial provider Bennett Lab
Growth protocol Cells grown overnight in liquid Spider media, diluted to 0.2 OD600, and grown to 1. Cells spun down and flash frozen in an ethanol/dry ice bath.
Extracted molecule total RNA
Extraction protocol RNA extracted using Ribopure Yeast Kit.
Label Cy5
Label protocol cDNA synthesized with Oligo(dT)20 + pdN9, with aa-dUTP/dNTPs using Superscript RT III. RNA hydrolyzed with 0.2M NaOH/0.03M EDTA and neutralized with 0.3M HCl. Samples cleaned using Zymo Columns. Sample dye-coupled in 0.1 M Na Bicarbonate, pH 9.0 and adding 1.25uL Cy5. Samples were incubated at room temperature for 1 hour in darkness and cleaned up using Zymo columns.
 
Channel 2
Source name Universal Reference
Organism Candida tropicalis
Characteristics reference: White and Opaque isolates of CAY1504 (white) and CAY2275 (opaque), RNA samples mixed
Biomaterial provider Bennett Lab
Growth protocol Cells grown overnight in liquid Spider media, diluted to 0.2 OD600, and grown to 1. Cells spun down and flash frozen in an ethanol/dry ice bath.
Extracted molecule total RNA
Extraction protocol RNA extracted using Ribopure Yeast Kit. RNA from 8 samples combined to comprise universal reference sample.
Label Cy3
Label protocol cDNA synthesized with Oligo(dT)20 + pdN9, with aa-dUTP/dNTPs using Superscript RT III. RNA hydrolyzed with 0.2M NaOH/0.03M EDTA and neutralized with 0.3M HCl. Samples cleaned using Zymo Columns. Sample dye-coupled in 0.1 M Na Bicarbonate, pH 9.0 and adding 1.25uL Cy5. Samples were incubated at room temperature for 1 hour in darkness and cleaned up using Zymo columns.
 
 
Hybridization protocol 300ng of Cy3 and Cy5 samples were mixed together in a total volume of 25uL ddH2O, heated to 95C for 3 min, and cooled to room temperature. 25uL GE hybridization buffer was added to samples, mixed, and spun down. 40uL of hybridization sample was loaded onto slide, slide sealed, and incubated at 65C rotating at 10rpm for ~17 hours. Slide washed using Agilent Wash Buffers and Drying and Stabilization Solution.
Scan protocol Scanned using Axon 4000b scanner, pixel size = 5 um, Lines to average = 2, Focus position = 15. Scanned for count ratio = 1.
Data processing Data normalized using Goulphar. Mnorm value converted from log2 change by using 2^n of Mnorm Value, which yields the value in the PRE_VALUE column.
