Usually, people working with short as well as long peptide sequences first dissolve it in either HFIP or DMSO to make sure that all the molecules are in monomeric form. But for my short synthetic peptide sequences containing all hrydrophobic amino acid residues neither of these works. While dissolving it in HFIP or DMSO we don't get transparent solution, which creates problems for self-assembly studies. How this problem can be resolved?
