    Sequence and Mutation Analysis Service of Unknown Proteins or Pe

      In drug development and the production of biological products, it is essential to ensure that proteins are correctly folded and functional. Sequence mutations, whether from errors in DNA replication or incorrect amino acid incorporation during translation, can cause protein dysfunction or inactivation. Accurate identification and analysis of these sequence variations (SVs) are critical for maintaining the quality and efficacy of products. Our services are tailored for analyzing sequence and mutation in unknown proteins or peptides, utilizing cutting-edge mass spectrometry to thoroughly examine variations in the primary structure of proteins.
