What is the significance of differential leukocyte counting?
Differential leukocyte counting is important for diagnosing infections, inflammation, anemia, and leukemia.
How does mdPCR compare to traditional methods?
mdPCR provides comparable results to immunofluorescent staining but is more cost-effective and does not require fresh samples.
What are epigenetic markers?
Epigenetic markers are modifications on DNA that can influence gene expression without changing the DNA sequence.
Can this method be used in clinical settings?
Yes, the flexibility of mdPCR may facilitate its translation into clinical use.
Who demonstrated the procedure?
The procedure was demonstrated by Christina Nassif, a technical officer from NRC's Medical Device Research Centre.
What are the advantages of using a microfluidic device?
Microfluidic devices allow for precise control of droplet generation and multiplexing capabilities.
