Neutral peptides usually dissolve in organic solvents. First, try to add a small amount of acetonitrile, methanol, or isopropanol. For very hydrophobic peptides, try to dissolve the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.
Although the hydrolysis of a peptide bond is energetically downhill, this process is very slow at normal temperature and pH. A group of chemists measured this rate, and found that a simple peptide bond between two amino acids in water and room temperature has a half-life of several years. (Kahne & Still 1988) For example, hair and wool, which are composed almost entirely of protein, can remain in water for weeks and not break down.
