At the near neutral pH of NaHCO3 solutions, both COOH-groups of the folate Glu (I assume that you are talking of the mono-Glu form, not the poly-Glu present in cells) will be ionized, so unless you expect specific interactions with the HCO3-, simply use the published solubility for the disodium-salt. _______________________________________________ Methods mailing list [email protected] http://www.bio.net/biomail/listinfo/methods
