Prof. Scott McLuckey (Purdue) developed a combination of novel instrumentation and ion chemistry, which allows simplification of mass spectra, hence rapid protein identification
�Fingerprint� of the protein ubiquitin
Identification of the compounds is based on molecular weight and partial structural information derived from gaseous protein ions as shown in the following example:
Spectrum of dissociation products
At Indiana University, Prof. David Clemmer is making rapid identification of proteins a priority for today�s analytical instrumentation
One of the instruments developed by David Clemmer combines the advantages of a variety of instrumentation types resulting in capabilities such as high sensitivity ultra-fast analysis structural ID unattainable by other individual instruments:
