PerfectHyb™ hybridization solution contains an accelerator that improves the hybridization efficiency and background. The hybridization rate is accelerated and background hybridization minimized. The solution facilitates Southern and Northern blotting analysis.


  • Efficient and sensitive RI and non-RI detection by Southern and Northern blotting analyses.
  • Reduces hybridization time from 16 to 1-2 hr.
  • Over night hybridization significantly increases the sensitivity on detection of low levels of expression mRNA by Northern blotting analysis.
  • Low viscosity and no generation of precipitates at room temperature.
  • It is not necessary to add salmon sperm DNA.
  • Hybridization and washing steps are performed at the same temperature.


  • Southern blotting
  • Northern blotting
