This study introduces a rapid DNA construct analysis method using Pyrosequencing technology. The technique efficiently identifies sequence errors, including deletions, in cloned DNA, simplifying clone checking.

Area of Science:

  • Molecular Biology
  • Biotechnology
  • Genetics

Background:

  • Accurate verification of DNA constructs is crucial for molecular biology applications.
  • Traditional clone checking methods can be time-consuming and labor-intensive.
  • Pyrosequencing offers a potential solution for rapid sequence analysis.

Purpose of the Study:

  • To develop and validate a simple and fast method for clone checking.
  • To assess the efficacy of combining Pyrosequencing with a preprogrammed nucleotide dispensation strategy.
  • To analyze DNA constructs for the production of recombinant apyrase.

Main Methods:

  • Utilized Pyrosequencing technology for DNA analysis.
  • Implemented a preprogrammed nucleotide dispensation strategy.

  • Applied the method to analyze N-terminus regions of plasmids for recombinant apyrase production.

    • Main Results:

    • Successfully analyzed ten plasmid constructs.
    • Identified seven correct constructs.
    • Detected sequence artifacts in three constructs: one with a single base deletion and one with a 195 bp fragment deletion.
    • The method accurately identified sequences downstream of deletions.

    Conclusions:

    • The combined Pyrosequencing and preprogrammed dispensation strategy provides a simple, fast, and accurate method for clone checking.
    • This approach effectively identifies both the location and nature of sequence artifacts in DNA constructs.
    • The method enhances the efficiency of molecular cloning workflows.
