Guidelines for selecting the purity of custom peptides based on their intended use

Please select the desired purity (≦) from the following options. We also offer purity guarantees via HPLC to accommodate various research needs for other purities and synthesis scales. Please feel free to consult with us regarding immunological purity (Crude), 70%≦, 80%≦, 90%≦, and 95%

Peptide dissolution and storage methods

Storage Methods

  • Peptides are delivered in a lyophilized (freeze-dried) state. Upon receiving the peptides, store them in a dark place at 2-8℃ or below this temperature.
  • Lyophilized peptides are stable at room temperature for a few days to weeks, but if you plan to store for a longer period, we recommend storing them at -20℃ or below.
  • Humidity can degrade peptide stability. When using peptides stored in a freezer, ensure they return to room temperature sufficiently before use.

Dissolution Methods

  • There is no universal solvent that can dissolve all lyophilized peptides, but it must be compatible with the biological assay.
  • You may need to try multiple solvents to find the suitable solvent. To select the most appropriate solvent for your peptides, some trial-and-error may be necessary.
  • The first chosen solvent may not work, so it is good to first try solvents that can be easily removed by freeze-drying. Therefore, it is important to perform solubility tests with a small amount of peptide before dissolving all of the peptide.
