Based on experience from production of tenths of thousands of different peptides on the preparative scale we can make fairly educated predictions of the difficulties that may be encountered in production of a given peptide. If we spot a problem peptide in your orders or requests, we will issue warnings and offer constructive advice on modifications of the sequence that may improve synthesis and/or handling after purification.
For peptides that are reasonably manageable in terms of synthesis and purification, you will find our prices to be very competitive. For Peptide synthesis ordering or quotation, simply use our contact form or send us an email at peptides@schafer-n.com listing your sequences together with information about the desired amount and purity. We will respond to your mail within 12 hours.
