Easily profile enzyme substrates

ProtoArray® Human Protein Microarrays are an excellent method to identify enzyme substrates. Using this method you can profile your purified enzyme or cell lysates against 9,000 functional proteins and identify possible targets. Since the identity of every protein on the array is known, you can immediately identify any proteins that your protein modifies. The protocol has been adapted to study numerous modifications including phosphorylation, methylation, ubiquitination, SUMOylation, NEDDylation, and nitrosylation.

Unlike other systems for analyzing protein modification, the enzyme substrate profiling application allows researchers to discover and identify new targets in as little as one day. In addition to testing enzyme activity, inhibitors and other compounds can be added to the assay to profile their effect on the enzyme substrate profile. This technique allows researchers to rapidly assess the specificities of drugs on enzymes.

The ProtoArray® Enzyme Substrate Profiling application is available either as a custom service or as a product.
