Insights into qPCR: Protocol, Detection Methods, and Analysis
2023年11月8日 · RT-PCR vs. qPCR. Reverse transcription PCR (RT-PCR) is often confused with real-time PCR. RT-PCR utilizes a reverse transcriptase enzyme to convert ribonucleic acid (RNA) into complementary DNA (cDNA). 1 When combined with qPCR, the method is called reverse transcription real-time quantitative PCR . 3 RT-qPCR is a powerful tool because it enables …
Infographic: The Cre-lox System Explained | The Scientist
2023年12月4日 · C re-loxP recombination allows scientists to excise, insert, or invert specific DNA segments with unprecedented accuracy. 1,2 This works through two key components: a Cre recombinase and loxP sequence recognition sites. The Cre enzyme identifies pairs of loxP sites (arrowheads), which flank (flox) the DNA, and catalyzes reciprocal DNA recombination …
