"Over the past 8 years we have used NEP for synthesis of many hundreds of peptides. The quality of NEP’s product is consistently very high. The company is deeply knowledgeable in all aspects of peptide synthesis, highly collaborative, and keenly interested in meeting the changing needs of their customers with respect to scale and formatting for delivery of peptides. One example is their flash-purified product which meets the need for initial draft-level evaluation without breaking the bank. Our experience with NEP’s antibody production capabilities has also been very good..."
