- 技術優勢
- URT for all tested transcriptsmRNA specific PCRStandard RNA isolation techniques are acceptable – no additional purification stepsMultiple transcripts can be amplified from one total RNA sampleStandard housekeeper reference transcripts (i.e. β-actin, GAPDH) are valid controlsUsable with standard RT-PCR strategies/kits – only primers differQuantitation of low copy transcripts in small tissue samples is feasibleSensitivity similar to standard RT-PCR protocols
- 技術應用
- Gene expression assays, from traditional to microarraysQuantitative RT-PCR applicationsGene regulation researchGene expression phenotyping of cells and tissues for research or clinical molecular pathologySmall sample (e.g. micro dissection) or single cell expression assaysInter-individual expression phenotyping for disease susceptibility
- 詳細技術說明
- The system has been readily employed in the common and currently used qualitative and real-time quantitative PCR protocols assessing gene expression in small samples of human tissues. The strategy has therefore proven to be universally applicable to all tested transcripts in all tested gene-expression assay contexts.
- *Abstract
-
Researchers have devised a novel reverse transcription strategy that utilizes a mRNA-specific RT primer designed to be universal for all mRNA transcripts. The employment of the mRNA-specific RT strategy obviates the limitations posed by total RNA preps contaminated with gDNA. Subsequent PCR is performed integrating features of the universal RT primer design, and is not complicated by the presence of gDNA nor pseudogene. Messager RNA can thus be amplified very specifically in the setting of gDNA contamination, without further steps. Purification of total RNA to mRNA becomes unnecessary, a particularly critical advantage when handling small tissue samples, as in human tissues. Both DNase treatment after RNA isolation, and no-RT controls in the PCR step to assess the presence of pseudogene, become unnecessary. Standard reference “housekeeper” transcripts such as β-actin and GAPDH, otherwise contaminated by gDNA-encoding pseudogenes, can be amplified specifically and quantitatively. Multiple transcripts can be amplified from the same total RNA aliquot, maximizing the efficiency of reverse transcription on limited RNA samples.
