Intercalating Dyes or Fluorescent Probes For RT-qPCR?

The unique feature of real-time quantitative polymerase chain reaction (RT-qPCR) is that it associates the amplification of your target gene with a fluorescent signal in a quantifiable manner. Presently, there are numerous fluorescent tool kits/methods to consider when designing your RT-qPCR experiment. However, the two major categories to choose from are fluorescent intercalating dyes and…

How to Choose the Correct Reverse Transcription Method

Quantitative Reverse transcription PCR (RT-qPCR) is frequently used in the lab to detect and quantify RNA expression in a sample. The first step of the assay is to convert the labile RNA to its complementary DNA (cDNA) counterpart through reverse transcription (RT). In fact, RT is the first step in a variety of molecular biology…

What Is a Ct Value?

When conducting real-time PCR, you’re looking for the exact amount of a target sequence or gene in your sample. During the PCR reaction, you measure its progress by accumulation of a fluorescent signal during amplification. But there’s also a lot of background fluorescence, which you want to bypass in order to glean meaningful information from…
