Protein is an organic macromolecule that undertakes the life activities of the body and is composed of the most basic unit of amino acids. The order of amino acids in the protein peptide chain is the primary structure of the protein. The amino acid sequence of each protein is unique, and the primary structure determines the higher-order structure of the protein, which in turn determines the function of the protein. After years of development, Creative Proteomics has accumulated rich experience in mass spectrometry detection, and provides protein identification services from protein separation, enzymatic hydrolysis, mass spectrometry detection to database construction and functional analysis for researchers around the world.
The basic process of protein mass spectrometry identification is first to digest proteins into peptide mixtures with protease, ionize the peptide mixtures by matrix-assisted laser desorption/ionization (MALDI), electrospray ionization (ESI), etc. Peptide ions with a specific mass-to-nucleus ratio are separated. Finally, the type and structure of the protein were analyzed by comparing with the theoretical mass spectrometry peaks.
The identification of proteins can help researchers fully understand the situation of protein species in a specific environment, and provide intuitive identification results of protein species for studying the occurrence and development of diseases and the growth and development status of animals and plants. Our service can not only identify and analyze cells, tissues, and body fluids, but also perform protein identification and analysis of protein bands in gel, spot, solution, and immunoprecipitation samples throughout the year.
The services we can provide are as follows.
This service can perform cleavage characterization, ligand binding, and modification analysis of various types of proteins such as protein conjugates and fusion proteins, and obtain protein type, molecular weight, structure, and other information.
This service enables a wide range of protein identification services for proteins in samples such as SDS-PAGE protein bands, protein spots, pull-down, and co-IP.
This service enables comprehensive identification of standard, chromatin, RNA, and other co-immunoprecipitated proteins for protein ID.
This service enables multidimensional capillary liquid chromatography separation and tandem mass spectrometry analysis of enzymatically digested peptide mixtures, resulting in final detection results.
This service uses mass spectrometry to analyze complex protein mixture samples, resulting in the accurate sequence of peptide fragments and the complete sequence of each protein.
