General description

Random Nonamers are random sequences of nine deoxyribonucleotides (9-mers) used to prime mRNA, with or without a poly(A) tail. Random nonamers may be used as universal, non-specific primers.

Application

Random Nonamers are suitable for:
  • First-strand cDNA synthesis
  • Preparing cDNA libraries (with oligo (dT) primers
  • Prepare labeled DNA probes for hybridizations

Features and Benefits

  • When preparing cDNA libraries or dealing with situations where specific primers are not suitable, the random nonamers can be combined with anchored oligo (dT)23 primers (Product No. O4387).
  • In cases of incomplete or missing sequence information, or when specific primers are not effective, the random nonamers offer a solution for cDNA library preparation.
  • The random nonamers′ priming capability at higher temperatures (up to 65°C) is reduced, ensuring that they do not interfere with polymerase chain reaction(PCR) following transcription.
  • Randomnonamers can also be used to prepare labeled DNA probes for hybridizationstudiesRandom nonamers serve as alternatives to specific reverse transcription (RT) primers for first-strand synthesis, cDNA library construction, and other applications.

Components

Random Nonamers are provided as a 50 uM solution in water.
