For what applications are Ultramer® Oligonucleotides useful?

Ultramer Oligonucleotides are high fidelity, long, single-stranded oligos of up to 200 bases. They are suitable for demanding applications such as cloning, DNA-directed RNA interference (ddRNAi), and gene construction, and can save researchers a great deal of time and trouble through direct synthesis of the en­tire target fragment. For example, Ultramer Oligonucleotides can be used to efficiently and quickly generate large insertions and deletions, or change stretches of sequence identity. They can also be used as templates for the synthesis of RNA in in vitro transcription or as DNA standards in qPCR.
