Bacterial Artificial Chromosome (BAC) clones enable precise human genome sequencing and analysis. BAC-based array comparative genomic hybridization (aCGH) protocols detail target generation, hybridization, and analysis for detecting genomic aberrations.

Area of Science:

  • Genomics
  • Molecular Biology
  • Cytogenetics

Background:

  • Bacterial Artificial Chromosome (BAC) vectors are crucial for human genome sequencing due to their stability and fidelity.
  • BAC clones provide accurate representations of genomic DNA segments.
  • Array comparative genomic hybridization (aCGH) is a powerful technique for detecting genomic copy number variations.

Purpose of the Study:

  • To describe protocols for BAC-based array comparative genomic hybridization (aCGH).
  • To enable the delineation of numerical aberrations and gene content using BAC clones and aCGH.
  • To provide tools for cytogenetic validation and fine mapping studies.

Main Methods:

  • Generation of targets for printing BAC DNA solutions onto glass slides.
