What are circulating microRNAs?
Circulating microRNAs are small non-coding RNA molecules found in body fluids that can serve as biomarkers for various diseases.
How does probe-based real-time PCR work?
It involves the use of fluorescently tagged probes that emit a signal when the target DNA is amplified during PCR.
What types of samples can be used for this method?
This method can be applied to plasma, serum, and other biological samples such as peripheral cells and tissues.
Why is visual demonstration important in this protocol?
Visual demonstrations help clarify complex steps that may be difficult to understand through written protocols alone.
What diseases can be studied using this method?
This method can be used to study various diseases, including cancers and diabetes, by quantifying relevant microRNAs.
