Application Notes

Cost-Effective Automated Phosphopeptide Synthesis on the Prelude™ Using Single-Shot™ Deliveries

The use of specially modified amino acids is available for a wide variety of peptide synthesis applications. These modified monomers are frequently extremely expensive and their implementation is limited by these costs.



Multivariable Individual Heating Conditions Tested in Parallel Provide Rapid Process Optimization on Prelude X

The application of heat represents a useful tool to optimize the production of challenging synthetic peptides, and a new technology, induction heating, has been introduced on the Prelude X.
