  • Contains a proprietary blend of hybridization accelerators and blocking agents to enhance the levels of hybridization
  • Supplied in one bottle containing 125mL
  • Use less probe per blot
  • Decrease hybridization time to 2 hours
  • Using standard hybridization buffers, only 1 to 5% of target molecules on a blot hybridizes to probe, making blots a relatively insensitive method for nucleic acid analysis (Vernier et al. (1996) Anal Biochem 235: 11-19)
  • With ULTRAhyb™ Ultrasensitive Hybridization Buffer, the hybridization reaction approaches completion, so that as few as 10,000 molecules can be detected
  • It works well with oligonucleotides having Tms from 78° to 90°C and 47 to 62% GC contents; However, the optimal hybridization temperature for oligonucleotide probes with different GC content and Tm values should be determined empirically
