The lyophilized peptide and peptide solutions should be stored at –20 °C when not in use. For long-term storage (over one year), it is recommended that peptides be stored at –80 °C. Lyophilized powders are generally more stable than peptide solution.
In addition, freeze-thaw cycles should be minimized, especially for peptide solutions. For periodic use of the peptides, it is highly recommended to prepare aliquots of peptide solutions and thaw only the aliquots needed to for experiment. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
