The Thermo Scientific North2South Hybridization and Detection Kit combines a novel enhanced luminol substrate for horseradish peroxidase (HRP) with optimized pre-made hybridization and blocking buffers to ensure consistent results and high sensitivity. Any nucleic acid blot can be hybridized with the appropriate biotinylated (biotin-labeled) oligonucleotide probe. After a brief membrane blocking step, the biotin label is detected with streptavidin-HRP and a 5-minute incubation with the chemiluminescent substrate. Results are easily recorded by brief exposure to X-ray film (1-15 minutes) or CCD camera.


  • Sensitivity equal to or greater than 32P
  • Amenable to many formats
  • High level of light output and consistent low background allows for very short exposure times using cooled CCD camera systems or film
  • Ready-to-use buffers and short process time makes switching from radioactive detection to chemiluminescent detection an easy transition, even for the novice user
