"Disulfide bond is a covalent bond formed between the sulfur atoms of two cysteines. This bond is crucial for the stability and function of proteins, and many secreted proteins or proteins that are located at the cellular surface have formed disulfide bond to maintain the stability. To meet specific research needs of our customers, MtoZ Biolabs provides disulfide bond analysis service at both single protein level and proteome level. We have optimized our sample preparation method to reduce the chance of in vitro disulfide bond exchange and maintain the native protein structure to the greatest extent. MtoZ Biolabs has developed a specialized platform, equipped with Q Exactive HF (Thermo Fisher), Orbitrap Fusion, and Orbitrap Fusion Lumos mass spectrometers, equipped with Nano-LC for disulfide bond analysis service. To better solve your research problems, we offer an all-inclusive service, including sample preparation, protein purification, digestion, peptide separation, LC-MS/MS analysis, pLink-SS software analysis and bioinformatics analysis. All you need to do is to tell us your project objective, and send us your cell/protein samples, and we will complete all the following experiments. Details about disulfide bond protein. "
