Protein Identification
PROMICFINDER Platform for Protein Identification and Quantification
The combination of high-performance liquid chromatography and high-resolution tandem mass spectrometry (LC-MS/MS) has emerged as a powerful and universal method for the global measurement of proteins. Unlike traditional western-blot or ELISA methods, MS-based technology can identify and quantify protein mixtures simultaneously on a large scale. For interested proteins without an available antibody, MS-based protein identification is the fastest and most reliable approach.
