Peptide synthesis - FAQ

Dispatch time will vary with length, scale, purity, and modifications ordered. Our average turn around time for 15-20 aa peptides, 25 mg with purities>95% is approximately 3 weeks.

Yes, we may vial your peptides under any particular conditions. Please contact us with your requirements and we will quote a very competitive price.

We routinely synthesize peptides with cys-cys disulfide bridge cycles or head to tail lactam cycles.

 We routinely prepare custom peptide libraries in 96-wells micro plate formats, fully MS caracterized. Please contact us with your project details and we will quote a very competitive price.

Yes, we do have a special offers for larger orders that you may benefit from and thus gain substantial savings for your order. Please contact us with your requirements and we will quote a very competitive price.

Aqueous solution solubility of peptides is not a predictable characteristic. As detailed in the Peptide storage handling guidelines, for unknown sequences we would recommend 1 to 10 mg/ml initial attempt in sterile water.

Every peptide undergoes stringent quality control procedures including analytical HPLC and mass spectrometry which accompanied all peptides.

While lyophilized at 4°C is acceptable for short term storage, we recommend as optimum long term storage: Lyophilized at -20°C. Please review our Peptide storage handling guidelines for more details.
