Dear netters,
1) What is the best method to get 17-mer and 20-mer oligos in aqueous
solution (that have been used for sequencing) back into a powder form?
2) What kind of recovery does one get when one precipitates 17-mer and
20-mer oligos using (a) ethanol and (b) isopropanol ? Are there any
carriers that would help in getting a better recovery? 
Thanks in advance
Anand Bachhawat
