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.

Custom Peptide Synthesis

We routinely synthesize custom peptides up to 40 amino acids in length using advanced solid support chemistries (FMOC and/or BOC) and purify peptides via HPLC. All peptides are subjected to extensive QC using analytical HPLC and mass spectrometry. We also provide additional analysis upon request.

A variety of purity levels, amounts (mg-gram), and modifications (including, FRET, C-terminal aldehyde, phosphorylation, and multiple disulfide bonds) are available.

PEPscreen®: Custom Peptide Libraries

The PEPscreen® peptide library is customized and configured in a convenient plate format, perfect for screening applications, epitope mapping, and peptide microarray production facilitating drug discovery, vaccine development, and protein interaction studies.

We have developed a proprietary, state-of-the-art synthesis platform to cater to the requirements of scientists for custom peptide libraries in a flexible format. It enables the parallel synthesis of small-scale, high-quality peptides—delivered fast.
