Thermo Finnigan Adds SALSA to its Proteomics Software Offerings

Premium

Thermo Finnigan has agreed to exclusively license the SALSA (Scoring Algorithm for Spectral Analysis) algorithm from the University of Arizona in Tucson. The company expects to include the algorithm as an enhancement to its proteomics software offerings in 2002.

Financial terms of the licensing agreement were not disclosed.

SALSA identifies specific characteristics of modified peptides in MS-MS spectra in order to automate spectral evaluation. Daniel Liebler led the development of the algorithm in a collaborative effort between the University of Arizona’s College of Pharmacy, its Southwest Environmental Health Sciences Center, and its department of computer science.

According to Thermo Finnigan, SALSA enables superior discrimination between a protein’s variant peptide forms, which will make it possible to identify protein modifications and sequence variations more quickly.

“Diseases and disorders can often be traced to complications involving protein modifications and variant sequences,” said Ian Jardine, president of Thermo Finnigan, in a statement. “The ability to find errors in these processes more quickly — especially in complex biological samples — can help speed the efforts of medical researchers to develop effective diagnostic and therapeutic tools.”
