Sample GSM4879207 Query DataSets for GSM4879207
Status Public on Apr 13, 2021
Title C. albicans SN250 Biofilm Growth in Spider Glucose Replicate 2
Sample type RNA
 
Channel 1
Source name SN250 spider glucose biofilm
Organism Candida albicans
Characteristics media: Spider glucose
growth: biofilm
Treatment protocol See Nobile et al. Cell 2012
Growth protocol Cultures for the extraction of total RNA under biofilm growth conditions were performed on biofilms grown on the bottom of 6-well polystyrene plates for 48 hours at 37°C and 200 rpm as previously described (Nobile et al. 2012). The media used was Spider 1% glucose, Spider and RPMI 1% glucose. Planktonic cultures for total RNA were grown in the same media by inoculating with cells from an overnight 30°C YPD culture to an OD600 of 0.05. Cultures were then grown in flasks at 37°C with shaking at 225 rpm until they reached an OD600 of 1.0.
Extracted molecule total RNA
Extraction protocol RNA was isolated and reverse transcribed as previously described (Nobile et al. 2012). Additionally, reverse transcription reactions were performed on either individual samples or on RNA in which an equivalent amount of each RNA sample was pooled.
Label Cy5
Label protocol cDNA was dried and resuspended in 5 μL 0.1 M sodium bicarbonate. An equivalent volume of Cy3 (pool) or Cy5 (individual) dye (Amersham) was added (dyes were resuspended in 60 μL of DMSO) and the reaction incubated at 65° for 20 minutes in the dark. Labeled cDNAs were purified using a Clean and Concentrator -5 kit (Zymo Research).
 
Channel 2
Source name pooled reference
Organism Candida albicans
Characteristics tag: pooled reference

Labeled cDNAs were purified using a Clean and Concentrator -5 kit (Zymo Research).
 
 
Hybridization protocol Equal amounts of the Cy3 and Cy5 labeled cDNA hybridized to the array overnight, as described in the Agilent protocol. Following hybridization, the arrays were washed as specified by Agilent.
Scan protocol Arrays were scanned at 5 μm, averaging 2 lines, with an Axon GenePix 4000A scanner.
Description sn250-sp-glu-biofilm-2
Data processing Arrays were gridded using GenePix Pro version 5.1. Global Lowess normalization analysis was performed for each array using a Goulphar script (The R Foundation for Statistical Computing). Normalized data was collapsed first by averaging the result for all duplicate probes and finally by taking the median of the probes for each ORF. Data was transformed as described for each experiment. Note that comparisons between arrays can only be made if they share a pooled reference (Ch2)
