For which applications is it better to order Ultramer™ sequences vs. short oligonucleotides?

The Ultramer product utilizes an enriched synthesis chemistry that has a higher coupling efficiency, and as a result, you receive a higher percentage of full-length product in your sample. These higher purity sequences are suitable for demanding applications such as cloning, ddRNAi (DNA directed RNAi), and gene construction and can save researchers a great deal of time and trouble in these applications through direct synthesis of the entire target fragment. Additionally, Ultramer oligonucleotides are a good choice for template synthesis due to the available lengths of up to 200 bases.
