    C-Terminal Sequencing Service

      Protein integrity is a crucial charateristics for protein, as protein truncation or microheterogeneity can lead to malfunction of protein. It is even more critical for the quality tests of biopharmaceutical products, such as antibodies and vaccines. Thus, analysis of the C-terminal sequence of protein products is necessary for evaluating the quality and function of protein products. MtoZ Biolabs have developed a LC-MS/MS system, which is suitable for analyzing both N-terminal sequence and C-terminal amino acid sequence and PTMs. We strictly follow the ICH Q6B Guidance to fulfill our customers’ needs.

      Applications

      1. Determination of N/C-Terminal Sequence of Proteins/Peptides/Antibodies/Vaccines

      2. Analysis of PTMs

       

      Sample Submission Requirements

      Format Gel bands, gel spots, and liquid samples are acceptable.
      Quantity Gel bands/spots that are visible to naked eyes are adequate for protein identification. For liquid samples, A total of 5-10 ug proteins are required.
      Purity Purity of liquid samples should be as high as possible. For liquid sample <10 ug, please avoid large amounts of detergent and salt ions, and note the buffer composition and the estimated amount of total proteins when submitting samples.
      Note All reagents/solvent used must be of the highest purity to reduce contaminating substances. Samples should be handled with extreme caution and always in clean condition. Any source that may introduce contaminating proteins should be eliminated.
