  • Quantitative reverse transcriptase polymerase chain reaction (QC RT-PCR) is crucial for gene expression analysis.
  • Accurate quantification of messenger RNA (mRNA) is essential for understanding cellular function and disease mechanisms.
  • Existing methods may lack efficiency or require complex protocols for high-throughput analysis.

Purpose of the Study:

  • To develop a novel, convenient, and high-throughput method for quantitative reverse transcriptase polymerase chain reaction (QC RT-PCR).
  • To enable real-time detection and quantification of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) target mRNA.
  • To establish a reliable internal control system for accurate mRNA quantification.

Main Methods:
