Sample GSM205366 Query DataSets for GSM205366
Status Public on Sep 01, 2007
Title B73 13 DAP endosperm tissue biological replicate 1
Sample type RNA
Source name Zea mays 13 day after pollination endosperm tissue
Organism Zea mays
Characteristics Stage: 13 day after pollination endosperm; Genotype: B73
Growth protocol Endosperm tissues were isolated from kernels of inbreds Mo17 and B73, and hybrids Mo17xB73 and B73xMo17 for gene expression analysis. Samples were collected during August 2005 from field-grown maize plants grown on the St. Paul campus Agricultural Experiment Station. Inbred and hybrid crosses were performed at three different dates to produce biological replicates. The crosses for all genotypes within a biological replicate were performed within 30 minutes of each other. Six ears of each genotypes were harvested at 13 DAP. Six endosperms were collected from each of the six ears and pooled for a total of 36 endosperms from each genotype by biological replicate combination. All tissues were flash frozen in a dry-ice cooled ethanol bath, and subsequently stored at −80˚C.
Extracted molecule total RNA
Extraction protocol RNAs for 13 DAP endosperm tissues were isolated using the plant RNeasy kit, according to the manufacturer’s instructions (Qiagen Corp., Valencia, CA). All purified RNA samples were quantified and qualified using the Nanodrop spectrophotometer (Nanodrop Technologies, Montchanin, DE) and agarose gel electrophoresis.
Label biotin
Label protocol Eight ug of total RNA was labeled for each hybridization using the One-Cycle cDNA Synthesis Kit, according to the manufacturer’s instructions (Affymetrix, Santa Clara CA).
Hybridization protocol Hybridization was performed according to the recommended Affymetrix protocols at the University of Minnesota Microarray facility.
Scan protocol The Genechip 3000 scanner was used to scan each array
