DNA Synthesis: Oligonucleotide Purification


The following purification options are available to the users of our DNA Synthesis services:

Description Synthesis Scale Oligonucleotide Length
Desalting 50 nmole, 200 nmole 3-75 bases
PAGE 100 nmole, 250 nmole, 1 umole 76-90 bases
PAGE 250 nmole, 1 umole 91-100 bases

For all of our in-house oligonucleotide products, we offer desalting as an add-on service. Our cartridge purification method efficiently removes salts, base protecting groups and short failure sequences up to 6 bases. Desalted oligonucleotides can be used for standard molecular biology applications including PCR, qPCR, DNA sequencing, etc.

For long unmodified oligonucleotides, we recommend PAGE purification. For this service option, both synthesis and purification will be provided through our partnership with IDT.
