Real-time PCR for mRNA quantitation.
Real-time PCR has become one of the most widely used methods of gene quantitation because it has a large dynamic range, boasts tremendous sensitivity, can be highly sequence-specific, has little to no post-amplification processing, and is amenable to increasing sample throughput. However, optimal benefit from these advantages requires a clear understanding of the many options available for runn...
متن کاملImproved mRNA quantitation in LightCycler RT-PCR.
BACKGROUND Real-time polymerase chain reaction (PCR) utilizing the LightCycler and similar systems is an increasingly used technique for quantitative reverse transcription (RT)-PCR of mRNA levels from genes of immunologic interest. A commonly encountered limitation with these systems is that the fluorescence induced by SYBR Green (a fluorophore that binds double-stranded DNA) can result from pr...
متن کاملRapid quantitation of mRNA species in ethidium bromide-stained gels of competitive RT-PCR products.
A rapid method for quantifying the low-abundant mRNAs of the low density lipoprotein receptor and the 3-hydroxy-3-methylglutaryl coenzyme A reductase by competitive polymerase chain reaction is presented. This approach requires neither special labeling nor blotting procedures. For each analysis, a defined amount of total cellular RNA is co-reverse transcribed and co-amplified with a titration s...
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 کاملA novel medium throughput quantitative competitive PCR technology to simultaneously measure mRNA levels from multiple genes.
There is a great demand for technologies to simultaneously measure mRNA levels from multiple genes. Here we report a new quantitative competitive PCR technology and demonstrate simultaneous quantification of mRNA from multiple genes. First, a sequential 2-fold dilution series containing equal amounts of gene-specific standard DNAs for 10-12 genes is prepared. Second, the serially diluted standa...
