New reagents enable optimal digestion, method development and instrument monitoring for LC/MS

Madison, WI USA. (26th June 2014) Promega Corporation announces the launch of new products for scientists working with mass spectrometry. The IdeS Protease enables fast, easy, high performance digestion of immunoglobulin, while the Human and Yeast Protein Extracts provide a test material for optimizing mass spec sample preparation. The new products add to the company’s existing range of proteases and services to improve mass spec sample prep workflows.

IdeS Protease is a recombinant, engineered version of the immunoglobulin-degrading enzyme from Streptococcus pyogenes. It is a highly specific protease that slices Immunoglobulin G (IgG) at a single, targeted site, offering 100% digestion in 30 minutes with no optimization. IdeS can be used to characterize therapeutic antibody candidates using LC/MS, and contains a histidine tag for easy removal. The versatile Promega IdeS enzyme cuts IgGs from a range of species, as well as Fc-fusion proteins.

The new yeast and human protein extracts are designed specifically for mass spectrometry applications. Available in either predigested, cleaned form for immediate use in LC/MS analysis or intact, undigested form to provide a test material for optimizing mass spec protein sample preparation, the extracts provide clean, consistent, quantified, model system samples for LC/MS method development and instrument monitoring. The yeast extracts are beneficial for users who prefer working with a relatively compact and well-studied proteome, whereas the human extract, with large dynamic range, provides the opportunity to work with complex proteomes. The new products are: MS Compatible Yeast Protein Extract, Digest; MS Compatible Human Protein Extract, Digest; MS Compatible Yeast Protein Extract, Intact; and MS Compatible Human Protein Extract, Intact.
