What would be the best solvent/buffer to dissolve a lyophilized peptide with a hydrophobicity gradient along the helix axis and the net charge of -1?

I have a 30 a.a. length lyophilized peptide which has a gradient of hydrophobicity along the helix axis and the net charge of -1 Which option is more important to determine the best solvent/buffer...
