BAC Microarray Service


BAC Microarray Service

Bacterial artificial chromosomes (BACs) are DNA constructs used for transforming and cloning in bacteria based on a functional fertility plasmid. BAC technologies are widely used in quantitative analysis, genomic DNA copy number analysis, physical maps constructing, and sequencing the genome of various organisms. In a BAC microarray (also known as BAC clone chip), probes are PCR amplified templates that are genome regions incorporated into a comprehensive BAC clone. BACs can clone a gene of 100-300 kb long, varied in size from 2400 to 30000 unique array elements. BAC arrays are outstandingly sensitive and precise, they can make a call on a single arrayed element. Thus, although BAC arrays have relatively few printed elements on the arrays, their spatial resolution is relatively high, but finite with large sequence variations compared with oligonucleotides, due to the length of BAC microarrays.

Creative Proteomics, as an advanced biotechnology company specialized in multi-omics analysis, provides top-ranking one-stop BAC microarray service. We will assist you with processes from the very first array and probe preparation to conducting meticulous testing, and finally delivering elaborate analysis report:

  • BAC clones selection from genome map;
  • Array DNA sample extraction and confirmation;
  • Array spotting;
  • Reference DNA and test DNA labeling, combining, and hybridizing;
  • Hybridized slide Image scanning;
  • Multiple software analysis.
