Background:

  • Large genomic DNA insert libraries are crucial for complex genome analysis, including physical mapping, positional cloning, and sequencing.
  • The bacterial artificial chromosome (BAC) system is the preferred method for cloning large genomic DNA inserts.
  • Decreasing costs of genomic analysis drive demand for high-quality, deep-coverage BAC libraries.

Purpose of the Study:

  • To present a detailed protocol for constructing high-quality, deep-coverage, large-insert BAC libraries.
  • To enable researchers to generate essential genomic tools for complex genome studies.

Main Methods:

  • Construction of bacterial artificial chromosome (BAC) libraries using a standardized laboratory protocol.
  • Focus on generating libraries with large insert sizes and deep coverage.
