 Peptide Storage
Peptides are delivered in lyophilized form and often hydroscopic. Absorption of water will decrease stability of the peptide and may reduce overall peptide content.
For results, please note:
---Maintain a dry environment and use a desicator.
---For storage, peptide should be kept frozen at -20℃ for maximum stability.
---more peptides containing Trp, Met, Cys, Asn or Gln have limited lifetime. Long-term storage is not recommended.

 Solubility
Different peptides will have different solubilities, based on the content of the peptides. As a general rule, peptides should first be dissolved in distilled, preferably sterile water, If solubility still remains a problem, try the following steps:
---Dissolve peptides in an appropriate buffer: acidic peptides or proteins in basic buffer and basic peptides in acidic buffer. If necessary, the solution can be sonicated briefly.
---It is also recommended that the peptide be dissolved to the possible concentration, and then diluted with water or buffer to the working concentration.
---Peptides containing Trp, Met or Cys require special care to avoid oxidation. Oxygen-free water or reducing agents can be used.

 Preparation for Use
When preparing the peptide for use, please observe the following steps to maintain peptide quality:
--Warm up the peptide to room temperature prior to opening and weighing out portion of the peptide.
--Weigh out desired quantity of peptide quickly then reseal vial tightly.
--Store the remaining peptide in freezer, preferably below-20℃ and under dry conditions
