Insights into qPCR: Protocol, Detection Methods, and Analysis
Nov 8, 2023 · 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 researchers to measure gene expression of ...
The Cre- loxP System: A Powerful Tool in the Genetic Toolbox
Dec 4, 2023 · Sternberg pondered about the underlying mechanism; he suspected that there must be a genetic hotspot for recombination located at the terminal ends of the linear genome to facilitate plasmid cyclization. 1 . The genesis of Cre-loxP recombinationConsistent with his hypothesis, Sternberg’s experiments revealed a small fragment of P1 DNA at the end of the genetic map that was likely responsible ...

Optimizing PCR: Proven Tips and Troubleshooting Tricks
Feb 23, 2024 · Template DNA. Template amount, source, and secondary structures or GC-rich regions may affect the reaction. 7. The amount of template depends on the DNA copy number. For a standard PCR reaction with 25-30 cycles, roughly 10 4 copies of the template DNA are sufficient to generate a detectable amount of PCR product. 7; The DNA required for a given reaction also depends on the source.

May 28, 2024 · UNIVERSE 25: John Calhoun crouches within his rodent utopia-turned-dystopia that, at its peak, housed approximately 2,200 mice. Calhoun was studying the breakdown of social bonds that occurs under extreme overcrowding, following up on his earlier discovery of the learned "behavioral sink" phenomenon in rats. 1
