What is RT-PCR? (Real-Time PCR & Reverse Transcription PCR)
Ғылым және технология
RT-PCR can mean either Real-Time PCR or Reverse Transcription PCR. In this video, I explain how both techniques work, and what kinds of questions can be answered with each technique. This video is an introduction to the conceptual basis of both RT-PCR techniques, it is not a practical how-to.

I totally agree
I'm suspecting this will be one of those channels that will be incredibly successful in years to come. Growth will be slow especially on KZread, but if you continue producing incredibly informative and quality explanations like this, I'm sure you will go far. You explained this concept perfectly. Thank you!

Thank you for the lovely compliment! I'm glad my video was helpful.
The MIQE guidelines published in Clinical Chemistry in 2009 clarify this issue: RT-PCR is reverse transcription PCR. Real-time quantitative PCR is qPCR.
Being new to PCR and stuff, I was really finding it confused , especially after going through the literature. But here? It's a wow, never I had come across of such an explanation which not just cleared my confusions but paved a way for some novel research ideas. Ton of thanks. Warm appreciations and looking for more of this kind. Thanks again. Good day.
Thank you so much for this!! I needed to understand how exactly real time pcr worked for a case study I have to present in front of pathologists for school.
Incredibly clear, engaging, and informative video! I needed a quick refresher and I now am totally comfortable with the concept of RT-PCR and qPCR. Thank you for making this!

I owe you :( super thank you
Do you have a video explaining amplification techniques such as FRET, TaqMan, Molecular Beacon, and Scorpion Probe? HELP!
Sorry if I sound incorrect here, but through explaining Reverse Transcription PCR you explain how when you have regular DNA at the cDNA stage, does that imply you have left the Uracil in it, with not using RNAse H and Extending the DNA from the fragments to create a double stranded copy DNA of the original mRNA?
the RT PCR Test used for Covid-19 - Though it is easy to trace the discovery of Reverse transcriptases to Howard Temin , and its independently isolation by David Baltimore in 1970, and it is also very easy to identify the inventor of underpinning PCR Test as Kary Mullis, I have yet to identify a scientist or group of them that take the credit for each of the RT PCR Test (real Time vs. Reverse Transcription). Do you know? Does anyone know?
Helloo, so we know that DNA polymerase cannot use RNA as a template to build a complementary strand. What is the biological reason therefore? Is it due to structure or direction of activity?
So can you use primers for specific genes that code specific proteins and then use RT PCR in both its meanings to quantify how much there is of each mrna?

i guess so, because that's exactly what i'm doing in my masters degree haha
You are not showing on your graph the number of copies. Like you said ten versus 10000 is not shown on the graph. I get the guicker plateau in fewer cycles and that of course means more copies for that sample, but it's not plotted on the y axis.
After complete reverse transcriptase and real time pcr,how we test the sample, validating it has sars cov 2?

If there is PCR product after reverse-transcription PCR, then there was SARS-CoV-2 in the original sample. If there is no PCR product, then there was no SARS-CoV-2 in the original sample.
can you recommend for me a book to understand the extraction of alkaloids or extraction in general? and thanks
