Best vectors for gene mapping (FISH)?

Click For Summary
SUMMARY

The discussion centers on the suitability of different vectors for gene mapping using Fluorescence In Situ Hybridization (FISH). The vectors mentioned include plasmids, cosmids, BACs (Bacterial Artificial Chromosomes), and YACs (Yeast Artificial Chromosomes). YACs are identified as the largest vectors, making them advantageous for mapping larger genes, while plasmids are derived from bacterial sources and are smaller. The choice of vector depends on the source of the gene and the specific requirements of the FISH technique, including expression promoters and the scale of the genes involved.

PREREQUISITES
  • Understanding of Fluorescence In Situ Hybridization (FISH)
  • Knowledge of vector types: plasmids, cosmids, BACs, and YACs
  • Familiarity with gene expression promoters
  • Basic concepts of prokaryotic and eukaryotic organisms
NEXT STEPS
  • Research the specific applications of YACs in gene mapping
  • Explore the differences in gene expression between prokaryotic and eukaryotic systems
  • Learn about the construction and use of BACs in genomic studies
  • Investigate the role of expression promoters in FISH experiments
USEFUL FOR

Geneticists, molecular biologists, and researchers involved in gene mapping and FISH applications will benefit from this discussion.

If you were to have clones of genes you wished to use for FISH in the form of a plasmid, cosmid, BAC and YAC, which would be best for gene mapping? I'm unsure as to what the distinction would be between these types particularly for use in FISH. Which is most commonly used and why?

Thanks

I will try to help.

Plasmids are from bacteria source,cosmid from viruse,YAC from yeast. So it depends from where and which gene are you want to see with FISH? Difference is expression promoters..ect,then there is an issue of scale or number of genes in those systems,YAC is biggest, so bacteria is procaryotic and yeast eucaryotic it is big difference as you probably know.
