    This study introduces a novel method for partially automating DNA sequencing analysis using fluorescently labeled primers. This approach simplifies data acquisition by detecting separated DNA fragments directly via computer.

    Area of Science:

    • Molecular Biology
    • Biotechnology
    • Genomics

    Background:

    • DNA sequencing is crucial for genetic research and diagnostics.
    • Current methods can be labor-intensive and time-consuming.
    • Automation is desired to increase throughput and reduce errors.

    Purpose of the Study:

    • To develop a method for the partial automation of DNA sequence analysis.
    • To improve the efficiency and accuracy of DNA sequencing.

    Main Methods:

    • Developed a method using fluorophores covalently attached to oligonucleotide primers.
    • Utilized distinct colored fluorophores for each DNA base (A, C, G, T).
    • Combined reaction mixtures and performed co-electrophoresis on a single polyacrylamide gel.
    • Detected separated fluorescent DNA bands near the gel's bottom.
