  • Utilizing r-32P-labeled primer in the second method for improved downstream base reading.

    • Main Results:

    • Adjusting ddATP and ddGTP concentrations improved band clarity in lanes A and G for the first method.
    • Modifying the ddATP/dATP ratio significantly enhanced band clarity in lane A for the second method.
    • Both methods, after modifications, produced more definitive sequencing bands.

    Conclusions:

    • Optimized chemical concentrations in RNA sequencing protocols can significantly improve band clarity.
    • Enhanced band readability facilitates more accurate interpretation of RNA sequencing data.
    • These modifications offer practical improvements for researchers performing RNA sequencing.
