Summary

This study introduces a faster multiple-color primed in situ labeling (multi-PRINS) method. By omitting a blocking step, researchers can simultaneously detect three chromosomes in a single cell within 90 minutes.

Area of Science:

  • Molecular Biology
  • Cytogenetics
  • Biotechnology

Background:

  • Primed in situ labeling (PRINS) is a technique for DNA detection.
  • Standard multi-PRINS requires a blocking step to prevent non-specific labeling.
  • This blocking step adds time and complexity to the procedure.

Purpose of the Study:

  • To develop a simplified and rapid multi-PRINS protocol.
  • To enable simultaneous detection of multiple chromosomes in a single cell.
  • To reduce the overall time required for multi-PRINS analysis.

Main Methods:

  • Omission of the ddNTPs blocking step between PRINS reactions.
  • Utilizing color mixing of fluorochromes (fluorescein and rhodamine) with labeled dUTPs (biotin and digoxigenin).

  • Simultaneous detection of three distinct chromosome targets.

    • Main Results:

    • A rapid multi-PRINS technique was successfully developed.
    • Simultaneous detection of three chromosomes was achieved with distinct colors (yellow, red, green).
    • The entire procedure was completed in under 90 minutes.

    Conclusions:

    • The developed protocol is efficient and practical for multi-PRINS.
    • This method allows for rapid, simultaneous detection of multiple chromosomal targets.
    • The technique has the potential for detecting even more than three chromosome targets.
