About Peptides International

Peptides International 
 
Peptides International was founded in 1983 by the late Professor Arno. F. Spatola to address the need for quality products and services in the field of peptide synthesis. Thirty years later, the company is recognized around the world as a trusted source of high purity, quality products ranging from innovative resins to complex custom peptide synthesis. Peptides International remains a private company, with Jacqulyn B. Spatola as the principal owner.

Today, in its laboratory facilities, the company has an active research and development program that complements its production of solid phase resins, amino acid derivatives, peptides, and related products. It has also been active in obtaining several Small Business Innovation Research (SBIR) grants that have supported the development of new products such as CLEAR-OX™ polymer-supported oxidants and targeted combinatorial peptide libraries.

 

Our Mission

Other exceptional products that we produce include: TAPI enzyme inhibitors, enzyme substrates (FRET, MCA, pNA), mini-PEG™ solubilizing linkers, CLEAR-OX™ polymer-supported oxidants, KLH, Click Chemistry, and combinatorial peptide libraries. A number of these and other products are produced under license from either universities or commercial sources.

cGMP

Peptides International, has formed a secure confidential global partnership that is designed to seamlessly take you from R & D to cGMP.

Each company brings distinct competencies and experience to the partnership. PI produces custom peptides across a wide range of technologies from multi-disulfide peptides to multi-step organic synthesis. It also offers an extensive portfolio of building blocks and other peptide synthesis tools. Our partner in turn, has developed and demonstrated over the years a unique set of expertise in the design of cost effective peptide manufacturing processes and in the cGMP production of clinical and commercial peptides APIs.

Key to the partnership is saving time and costs to customers by providing a seamless progression and transfer of technical information from peptide candidate screening through preclinical and clinical development.

Peptides International, under the leadership of Dr. Michael Pennington, has custom peptide synthesis expertise across a wide range of technologies ranging from multi-disulfide peptides to multi-step organic synthesis. The company also offers an extensive portfolio of building blocks and other peptide synthesis tools and its activities have been certified to ISO 9001:2015 standards.

Contact us today to find out how these technologies and efficiencies can utilized to take your R & D to cGMP, economically and successfully!
