Modeling and analysis of competitive RT-PCR.
The present studies demonstrate a theoretical and practical framework for the accurate quantitation of gene expression in RNA extracted from microscopic tissue samples. The approaches are developed around competitive RT-PCR techniques. Assay performance has been examined and validated at both the RT and PCR steps. Our analysis of RT transcription efficiency for a number of native and competitor...
متن کاملCompetitive RT-PCR: Estimation of Copy Number.
INTRODUCTION In this protocol, sample and competitor RNAs (previously synthesized as described in Preparation of Competitor RNA for Competitive RT-PCR) are reverse transcribed (separately) in a pilot experiment. A constant amount of sample RT product is then combined with a 2-logserial dilution of competitor RT product for PCR. This procedure provides an approximate copy number for the sample, ...
متن کاملCompetitive RT-PCR: Preparation of Competitor RNA.
INTRODUCTION The first step in competitive RT-PCR is the synthesis and purification of the synthetic competitor. This is an RNA molecule designed to be reverse-transcribed and PCR-amplified with the same efficiency as the endogenous transcript of interest. Once the competitor molecule has been prepared, as described in this protocol, competitive PCR can be carried out, as described in Comptetit...
متن کاملReproducibility in the quantification of mRNA levels by RT-PCR-ELISA and RT competitive-PCR-ELISA.
The use of reverse transcription (RT) PCR for relative quantitation of gene transcripts relies on the reproducibility of the individual RT, PCR and product measurement steps. Semi-competitive RT-PCR (RT-cPCR) uses an internal competitor template in the PCR step to improve quantitation. We have surveyed the reproducibility of RT, PCR, RT-cPCR and measurement, amplifying the glyceraldehyde-3-phos...
متن کاملSerial competitive RT-PCR using multiple standards.
PCR is widely used for the amplification of DNA and reverse-transcribed RNA. In recent years, real-time PCR has been introduced as a new technique for mRNA quantitation. However, because of the high cost of real-time PCR equipment and supplies, especially using custom-made probes, quantitative RT-PCR is a valuable alternative method. Several quantitative PCR protocols describe the use of a sing...
