Glycosylation Site Analysis Service

    The analysis of glycosylation sites in glycosylated proteins is of great importance for studying protein structure and function.


    MtoZ Biolabs provides a glycoform relative content analysis service based on LC-MS/MS. First, various enzymes are used to digest the protein, then in heavy-labeled H218O, PNGase F or various O-glycosidases are used to enzymatically release the glycans from the target protein. At this point, the glycosylated peptides will carry a 18O, and by searching the database, the glycosylation modification sites can be identified.

    Service Advantages

    1. Relatively Short Identification and Analysis Time

    2. High Sensitivity and Good Reproducibility



    1. Identification of N-Glycosylation Sites in Glycosylated Proteins

    2. Identification of O-Glycosylation Sites in Glycosylated Proteins


    Sample Submission Requirements

    1. If you provide tissue samples, please transport them to us on dry ice.

    2. If you provide protein samples, common tissue and cell lysis buffers can be used for protein extraction.

    3. Sample Transport: Please use an ample amount of dry ice and opt for the fastest possible mailing method to minimize sample degradation during transportation.
