Nonradioactive nucleic acid labeling methods offer safer, more stable, and cost-effective alternatives to radioactive techniques. The Universal Linkage System (ULS) provides advanced DNA labeling for molecular diagnostics.

Area of Science:

  • Molecular Biology
  • Biotechnology
  • Genetics

Background:

  • Radioactive nucleic acid labeling presents significant safety, disposal, stability, and cost challenges.
  • Nonradioactive labeling systems have emerged as superior alternatives over the past two decades.
  • Various nonradioactive methods include enzyme-mediated techniques and chemical labeling systems.

Purpose of the Study:

  • To review DNA-based molecular diagnostic applications of Universal Linkage System (ULS) technology.
  • To explore the future perspectives of ULS in molecular diagnostics.
  • To highlight advancements in nonradioactive nucleic acid labeling and detection.

Main Methods:

  • Discussion of traditional enzyme-mediated labeling (random priming, nick translation, PCR labeling).
