Unknown Protein Identification Service

    Unknown protein identification refers to the process of identifying, studying, and annotating proteins that are not fully understood in terms of function and structure. This process mainly includes protein molecular weight determination, amino acid sequence determination, structure prediction, functional analysis, and interaction network analysis. Mass spectrometry technology is an important method for identifying unknown proteins. Through the identification of unknown proteins, we can discover new biomarkers, drug targets, and treatment strategies, providing important information for disease prevention, diagnosis, and treatment.


    MtoZ Biolabs offers unknown protein identification services using the latest Thermo's Orbitrap Exploris 240 mass spectrometer combined with Nano-LC chromatography. This service enables efficient and precise mass spectrometric identification of unknown proteins in samples such as protein extracts, SDS-PAGE protein bands, 2D protein gel spots, pull-downs, and Co-IPs. The identification includes molecular weight, amino acid composition and arrangement, as well as post-translational modification information of unknown proteins.
