Purity & Yield

Purity is greater than 80%


depending on oligo sequence and structure. Refer to coupling efficiency table for oligo length dependent purity and yield.

No further purification required for PCR and sequencing applications.

Gel purification recommended for oligos above 50 mer and all applications involving cloning and mutagenesis.

**RPC is reverse phase purification using a cartridge; a substitue for HPLC.

Purity 85% to 95%


depending on oligo sequence and structure

Yield and Purity will be lower for sequences with high GC content

Not recommended for oligos longer than 35 mer.

**RPC is reverse phase purification using a cartridge; a substitue for HPLC.

Purity 98% to ~100%


depending on oligo sequence and structure

Yield will gradually decrease as length of oligo increases. Palindromes, hairpins and high GC content oligos and oligos containing stretches of 3 or more G's induce strong secondary structure and base stacking thus decreasing purity and yield.

*NR Not Recommended

*a. Typical yield stated in the table is for unmodified random sequence oligos. Reduction in yield is observed with high GC content oligos and those forming strong secondary structures.

b. Reduced yield is expected with modified oligos. The reduction percentage varies with modification type and number of sites. Typical reduction is 10%-20% per modified site.

c. Yield of 33µg/A260 unit for DNA oligos is calculated for an ~equimolar base composition. Long stretches of a single base or homopolymers will have variable yields. Example for homopolymeric 20 mer: dA(20) = ~25ug/A260 Unit; dC(20) = ~40ug/A260 Unit; dG(20) = ~32ug/A260 Unit and dT(20) = ~37 ug/A260 Unit
