MilliporeSigma
Custom Peptide Libraries configured in a convenient plate format; perfect for screening applications, epitope mapping and peptide microarray production.

Synthetic custom peptides are an important tool in drug discovery and proteomic research. Our service portfolio assists researchers in applications requiring high-quality custom peptides, peptide libraries and arrays. We routinely synthesize peptides up to 40 amino acids in length (inquire for longer lengths) using state-of-the-art solid support chemistries and purify peptides via HPLC. A variety of purity levels and modifications are available with scalable milligram to gram quantities to meet your research and translational needs.

Important Update

March 22, 2022: Please be advised of a recent strategic business decision in which we will be discontinuing our PEPscreen® Custom Peptide Library product offering. This notice provides several months for ordering preparation as well as validating an alternative supplier. Globally, the last order intake date will be September 30, 2022. It is our intention that by providing a 6-month discontinuation notice, you will have ample time to plan and establish business continuity. It has been a pleasure supplying you with this product.
