Area of Science:

  • Molecular Biology
  • Genomics
  • Biotechnology

Background:

  • Screening large yeast artificial chromosome libraries with polymerase chain reaction (PCR) is labor-intensive.
  • High-throughput screening methods are crucial for genomic research and clone identification.

Purpose of the Study:

  • To develop and implement automated, labor-reducing strategies for screening yeast artificial chromosome collections.
  • To enhance the efficiency and throughput of PCR-based screening assays.

Main Methods:

  • Library compression to reduce initial sample numbers (up to 12-fold).
  • Robotic assistance for DNA extraction and sample pipetting (BIOMEK 1000).
  • Integration of sample preparation with a high-capacity temperature cycler (576 reactions).
