Protein Mutation Analysis Service

    Protein mutation refers to the alteration in the amino acid composition or sequence of a protein, which subsequently leads to changes in the structure and function of the protein. Protein mutations can occur naturally or be induced artificially. The analysis of protein mutations primarily involves comparing the differences between normal proteins and mutant proteins, revealing the effects of mutations on protein structure, stability, function, and interactions with other molecules. In the fields of biotechnology and drug design, mutation analysis aids in understanding the molecular mechanisms of proteins, optimizing protein performance, predicting the impact of mutations on biological functions, providing a basis for biotechnology and drug design, and enhancing the production efficiency of bioproducts and the specificity of drug therapy.


    MtoZ Biolabs provides a one-stop, mass spectrometry-based protein mutation service utilizing Thermo's newly launched Obitrap Exploris 240 mass spectrometer combined with Nano-LC chromatography technology. Through high-resolution mass spectrometry analysis of protein amino acid sequence, it reveals whether the protein has been mutated or not, the site of mutation, and the amino acid sequences before and after the mutation, which can help research on the structure and function of proteins, the regulation of gene expression, and drug discovery.
