Yield Specifications
The tables below provide guaranteed minimum yields that depend on oligo properties
(length and modifications), synthesis scale, and purification method. Oligos excluded
from these tables may also be ordered, but specific yields cannot be guaranteed.
Minimum yields are given in units of optical density (OD), which is proportional
to oligo amount (the concentration in a volume of 1 ml). For more information, see
Calculations or contact
our Technical Support team.
Salt Free
Salt-Free is our basic oligo purity option and is appropriate for most unmodified
oligos used in many applications, including routine PCR, microarray fabrication,
and blotting.

HPSF® Purity
High purity salt free (HPSF) purification is a high-performance, high-throughput
purification that efficiently removes most N-1 and other truncated sequences created
during oligo synthesis. When using unmodified oligos in more sensitive applications
such as qPCR or DNA sequencing, HPSF delivers excellent yields and improved purity.
HPSF is available and recommended for oligos containing:
- IUB Wobbles (degenerate nucleotide sites)
- 5' Amino C6 Linker [Amino C6]
- 5' Phosphate [Phos]
- 5' Biotin-TEG [BioTEG] *
* 90 bases maximum length

QuickLC™ Purity
QuickLC purification: Twice the Yield in Half the Time of HPLC; Same Purity—Guaranteed!
QuickLC purification is a proprietary purification process that offers purity levels
of 85% and above*—equal to or greater than the levels obtained by HPLC purification.
Extensive testing in end user laboratories has proven that oligos purified with
the QuickLC method perform identically to oligos that go through the older HPLC
process. If you believe that your QuickLC purity oligos are not performing as good
or better than HPLC-purified oligos, call us and we’ll make it right.
The QuickLC process removes most N-1 and other truncated failure sequences created
during synthesis and achieves purity levels of 85% and above*. Selection of QuickLC
purification ensures delivery of your oligo at HPLC-grade purity; typically within
2 days!
QuickLC is highly recommended for oligos needing HPLC-grade purity or when higher
than typical HPLC yields are required for your experiment.

HPLC Purity
Standard High Performance Liquid Chromatography (HPLC) purification is recommended
for oligos that require additional purification, such as dual-labeled probes, Molecular
Beacons, and most modified oligos that cannot be purified by our QuickLC purification
method.
HPLC purification removes most N-1 and other truncated failure sequences created
during synthesis and achieves purity levels of 85% and above*. Oligos purified by
HPLC typically ship within 5 days. When faster delivery times are critical, Eurofins
MWG Operon encourages you to consider the QuickLC purification, where it is offered
for you oligo type.
Our oligo purification experts will determine and employ the optimum HPLC technique
for your specific oligos and select only the fractions containing the highest purity
for delivery to your lab. The techniques employed include (1) reversed-phase HPLC
purification that separates oligos on the basis of hydrophobicity; (2) ion exchange
HPLC that separates oligos on the basis of charge.

PAGE Purity
Polyacrylamide gel electrophoresis (PAGE) purification is recommended for oligos
that require the highest level of purification, and achieves purity levels for unmodified
oligos of 90% and above*. Although PAGE purification achieves the highest purity
levels available, recovery of the oligo from the matrix is an inefficient process
and results in lower final yields. Thus PAGE purification is not recommended as
a routine technique. PAGE purification also cannot be used for oligos shorter than
20 bases.
PAGE separates oligos on the basis of molecular weight and is performed on a denaturing
polyacrylamide gel prepared with stock solutions of acrylamide, urea, and TBE buffer.
The desired oligo band is detected through UV shadowing and the full-length product
is excised and eluted from the gel.
