To ensure accurate measurements, make sure that quantities of peptides are given as net weight rather than gross weight generally stated by regular suppliers. See SB-PEPTIDE peptide quantification service.

Peptides are routinely delivered with TFA salts, which could be toxic for in vivo and in cellulo applications. It is therefore desirable to switch to acetate or HCl salt form of peptide. Discover SB-PEPTIDE peptide TFA removal service.

Compare analytical methods used to assess peptides. Purity should be determined on HPLC analytical system using columns with 4 µm resolution or below. Get more information about our peptide quality control process.

Prefer solubility to be physically tested rather than theoretically. Discover all benefits included in our services such as free peptide solubility test.

Ask for several aliquots to prevent losing peptide material when initially facing a difficulty in solubilizing the peptide. The ultimate way to ensure stability of peptides is to have them stored under inert gaz.

It is recommanded to store lyophilized peptides at -20°C. The shelf-life of peptides in solution is very limited. Peptides that undergo multiple freeze-thaw cycles are susceptible to degradation. Discover our peptide handling and storage guidelines.

Choose the appropriate delivery service to deal with research deadlines and make sure that peptides are delivered with a certificate of analysis that attest the quality of the products in compliance to the requested specifications.
