Peptide Protein Chemistry Facility

The Peptide and Protein Chemistry Facility at the University of Colorado at the Anschutz Medical campus provides peptide synthesis, purification and peptide/protein composition analysis as well as mass spectrometry services for academic and industrial clients.

The Peptide and Protein Chemistry facility personnel help users choose and design experiments using appropriate chemistry/instrumentation, to obtain the necessary data, and interpret the results. The Facility also provides instruction for graduate students and postdoctoral fellows for the use of HPLC and LC/MS approaches.

The facility is equipped with state of the art instrumentation and technical support suitable for diverse applications and samples.
