[ccp4bb] DNA oligonucleotide purification

[Wallen, Jamie]

Title: DNA oligonucleotide purification

All,

Our laboratory is looking for a new column to purify short (40mers or less) DNA oligonucleotides that will be used for crystallization setups. I wanted to ask if anyone has suggestions of a column that will give excellent separation of N and N-1 products. We have a Shimadzu HPLC system. We are considering Dionex columns as well as Oligonucleotide Separation C18 columns from Waters, but if there are others that are better we would like to know. Any suggestions will be greatly appreciated. Thank you!
