De Novo Antibody Sequencing Services

CD BioSciences is equipped with the most advanced technologies, such as high-performance liquid chromatography (LC-MS/MS) coupled with tandem mass spectrometry and advanced calculation algorithms. CD BioSciences can provide accurate and rapid antibody de novo sequencing services according to your needs. CD BioSciences' services include variable regions, variable regions and leader regions, as well as full-length heavy and light chain antibody sequencing for all species, isotypes and allotypes. The purified multivalent form of monoclonal antibodies can be sequenced with 100% coverage of the desired area and excellent accuracy. Many successful cases from CD BioSciences have confirmed our qualifications and can provide antibody sequencing with 100% accuracy and satisfaction to meet customer needs.

Overall Solutions

Based on our proprietary technology for antibody de novo sequencing and our expertise in the field of protein mass spectrometry and informatics, CD BioSciences' standard service procedures include the following steps:

  • De novo antibody sequencing work flow chart 1 De novo antibody sequencing work flow.
  • First use various trypsins to digest antibody proteins into overlapping peptides
  • LC-MS/MS digestion, then fragment optimization
  • The feature of overlapping peptides is de novo peptide sequencing
  • Automated antibody sequence assembly using characterized peptides
  • CD BioSciences use the most advanced calculation algorithm for data analysis, which can effectively obtain the amino acid sequence of the digested peptide

Our Advantages

  • Customizable antibody fragment sequencing

We can choose to measure only the light chain, heavy chain or variable region of the antibody according to customer needs. In addition, sequencing of rare antibody subtypes such as conjugated antibodies and IgM can also be customized.

  • Low time spent

Technological innovation has brought about a reduction in time cost. The time cost of the DASS platform is less than half of that of traditional sequencing methods. After receiving the samples, the full sequence determination can be completed within 3-10 working days.

  • Low sample volume requirements

Only need to provide 25-100μg purified antibody.

  • Diverse types of sequencing

It can sequence fluorescently labeled monoclonal antibodies, IgMs, and other non-traditional antibodies.
