C18 Desalting Purification Cartridges

C18 Desalting Purification Cartridges

  • BrandCommaX

The C18 desalting purification cartridge is packed with octadecyl (C18) bounded silica gel. The octadecyl groups are very hydrophobic and have strong retention for nonpolar compounds. Thus DNA molecules can be retained while residual salts pass through, endowing you with the power to obtain high-purity DNA products.


C18 desalting purification cartridges can be used for desalting oligonucleotides after synthesis. During the purification process, failure sequences are eliminated and the DMT is subsequently removed, allowing for elution of purified products. Desalting purification cartridges can also be used for desalting oligonucleotides after purification by PAGE or HPLC.

Order information:

Biocomma provides C18 desalting purification cartridges with various sizes. An appropriate cartridge size can be chosen according to the concentration of oligos. If multiple samples are to be purified, the 96-well plate will be a better choice.
