Priveel Peptides will assure the complete confidentiality of all proprietary information we receive during the course of fulfilling any of our custom services.


Product Report

A complete QC report will be included with each delivered product such as HPLC profile, Mass Spectrometry and Synthesis Report. NMR, IR, UV, Elemental Analysis, Water Content and Amino Acid Analysis data will be available upon special request. But additional cost will be charged.


Significant discount will be offered for large/batch peptide orders or for first time customers.

Peptide Modification

Priveel Peptides create peptides with the exact conformation or characteristics needed for a given application through the addition of modifications. Peptides in general and specific amino acids have distinct moieties that are amenable to modification, including:
    N-terminal amino group
    C-terminal carboxy group
    ε-Amino group on lysine
    Hydroxyl group on serine, threonine and tyrosine
    Guanidine group on arginine
    Thiol group on cysteine
Priveel Peptides offer more than 500 N- and C-terminal and internal peptide modifications to give you the custom peptides that you need to propel your research forward. The following peptide modifications based on type to help you quickly determine which modification will best suit your needs.

Large Scale Peptide Synthesis

When compared to the Standard Peptide Synthesis Service, the Large-Scale Synthesis service maintains all the original features, such as guaranteed high purity and high success rate in synthesis of extremely long peptides (up to 200 amino acids). Furthermore, preliminary costing, project review, R&D, process optimization, and detailed qualification reports will be used to ensure the successful and efficient delivery of your peptides.

Key Features
1. One-on-one managing of each project
2. Process optimization of synthetic route
3. Highly ensured purity at >95%
