Bio-Synthesis has extensive experience with long oligo synthesis with high ratio of degenerate sites at at various ratio. provide the standard IUPAC wobble options, as well as custom wobbles (randomers) using machine mix option or custom hand mixture at each site in your oligonucleotide as specified by our customer. These degenerate bases are often used when PCR target is not available. Degenerate primer are often used when when a sequence from one species is the basis for amplication of a homologous region or gene in another species. Common Wobble Sites are:

Storage Conditions:
-20°C To -70°C Oligonucleotides are stable in solution at 4°C for up to 2 weeks. Properly reconstituted material stored at -20°C should be stable for at least 6 months. Dried DNA (when kept at -20°C) in a nuclease-free environment should be stable for years.
