Selected Real Time PCR/ RT-PCR Reagents Solutions

Real time PCR based analysis combines “traditional” end-point detection PCR with fluorescent detection technologies to record the accumulation of amplicons in “real time” during each cycle of the PCR amplification. Based on the advantages that 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, real time PCR is among the most valuable techniques applied in biological researches, which comprise basic science, biotechnology, medicine, forensic science, diagnostics and more.

Owing to years of continuing innovation and improvement, TransGen has built abundant experience on real time PCR/ RT-PCR technologies combining reverse transcription and DNA amplification, based on which, comprehensive real time PCR/ RT-PCR solutions can be provided to push forward researchers’ experiments.

 Greater specificity

Fig. 2 58 genes (9 human genes, 7 mouse genes, 17 rice genes, 8 tobacco genes, 4 Arabidopsis genes, 10 wheat genes and 3 maize genes) were amplified using products from TransGen, Company V, and Company T. The highest number of genes with no NTC amplification was obtained by TransGen's PerfectStart^® Green qPCR Supermix (AQ601).

 High amplification efficiency

Fig. 3 The amplification plot (left) and standard curve (right) resulting from the amplification of a dilution series of plasmid DNA (10 ng to 0.1 pg, 10-fold dilution) using PerfectStart^® Green qPCR SuperMix (AQ601). The amplification efficiency was 94.1%.

 High sensitivity

Fig. 4 β-actin was amplified from a dilution series of human cDNA obtained by reverse transcription (TransGen, AT311) from 500 ng of RNA (no NTC amplification), using the products from TransGen and Company T respectively. The results show that amplification sensitivity of TransGen's PerfectStart^®Green qPCR Supermix (AQ601) is comparable to the product from Company T.

Superior Performance of Real Time PCR/ RT-PCR Reagents

PerfectStart^® Green qPCR SuperMix (Cat. No. AQ601)

Amplification results for GAPDH, using PerfectStart^® Green qPCR SuperMix from TransGen and products from Company TG and Company V respectively, show that PerfectStart^® Green qPCR SuperMix lead to perfect S-shaped amplification curves and ideal melting curves with one sharp peak. The reproducibility of PerfectStart^® Green qPCR SuperMix is comparable with Company TG’s reagent and better than Company V’s reagent.
