Nucleotides isolation

[Byung-Hoon Kim]

Dear all,

To my knowledge, the general method for plant nucleotides isolation is under 
acidic condition (HClO4). After some clean up process, final nucleotides 
pellet is resuspended in 10 mM HCl for HPLC analysis.

But, because my target nucleotide (PAPS) is known to be very unstable under 
acidic condition, I'm wondering whether there are other methods for plant 
nucleotide isolation under neutral pH condition.

Any comment will be appreciated.
