摘要: The present invention provides methods for preparing nucleic acid samples. The methods of the present invention are particularly amenable for preparing samples that substantially represent the whole transcripts. In some aspects the methods include a step of reducing the amount of ribosomal RNA in a total RNA sample prior to amplification. In preferred aspects single stranded sense strand cDNA is generated, labeled and hybridized to arrays of probes. The method is particularly suitable to use with microarray based expression analysis.

摘要: The present invention relates to the amplification of nucleic acids, preferably from mRNA. A primer and promoter are added to a target sequence to be amplified and then the target is amplified in an in vitro transcription reaction and the product of this reaction is used as template for subsequent rounds of amplification. Polyadenylated control transcripts are added to the nucleic acid sample prior to the first step of amplification to monitor the efficiency of the amplification and labeling reactions.

摘要: The proportional amplification of nucleic acids can increase the amount of nucleic acids while preserving the relative abundance of the individual nucleic acid species, or portions thereof, in the original sample. A proportionally amplified nucleic acid preparation may be analyzed in a gene expression monitoring system, preferably involving a nucleic acid probe array.
