Custom Peptide Frequently Asked Questions

Can Invitrogen prepare peptides not described on the ordering form?
Our peptide chemists will evaluate any request to identify the best solution for our customers. By utilizing the whole of Invitrogen’s broad range of products and expertise, Invitrogen can provide a solution to most customer requests.

Can Invitrogen supply my difficult-to-make peptide?
Due to their sequences, some peptides are hard to make, or routinely provide low yields. Invitrogen’s peptide chemists can alter the synthesis conditions to increase the likelihood of success in these cases. Please provide any known information regarding difficult peptides. If Invitrogen’s peptide chemists believe there may be an issue during synthesis, it will be noted on your quotation. Occasionally, synthesis issues cannot be resolved. In the case of a failed attempt, the customer will not be billed. Invitrogen will only invoice for a successful attempt resulting in material that meets the customer’s specifications.
