Bioinformatics Analysis of Antibody Sequencing Data

Accurately acquiring antibody sequences is one of the most important prerequisites to achieving antibody functional optimization and expression of recombinant engineering antibodies. Antibody sequencing and analysis also plays a key role for researchers publishing articles and apply for patents. The data is even more critical for pharmaceutical enterprises to further their research and develop novel drugs. Synbio Technologies can quickly and accurately sequence and analyze antibody sequences with our advanced GenoTM Ab Platform. Using this platform, we can perform high quality de novo sequencing of multi-species’ (including mice, rats, Armenian hamsters, camels, rabbits, equines, bovines, canines, birds, etc.) monoclonal antibodies. The Syno® Ab Platform also has the capabilities to analyze data that may come from various antibody libraries and hybridoma technologies, making this platform very applicable. Additionally, our experienced bioinformatics analysis team can also provide professional data mining and annotation.

Synbio Technologies can utilize immune repertoire sequencing technology to selectively amplify the target region of T/B lymphocytes. By combining this approach with high-throughput sequencing technology and powerful antibody big data platform, we can comprehensively evaluate the diversity of the immune system. The combination of these technologies has been widely used in the rapid antibody preparation and disease and immune system surveillance, as well as vaccine optimization. In addition to providing the genetic sequences of the monoclonal antibody, we can also express and purify antibodies by utilizing our NGTM Codon Optimization Technology and Syno® DNA Synthesis Platform.

Case Study

Synbio Technologies’ immune repertoire sequencing and bioinformatics analysis:

  1. Library Construction
    Synbio Technologies performed 5’ RACE reverse transcription of the extracted RNA, amplified, and constructed the library.
  2. Library Quality Control
    The Qubit 2.0 Fluorometer was used to perform preliminary quantification after the library construction. After dilution, insert size detection was performed on the library based on the Agilent 2100 bioanalyzer. Only when meeting expected requirements, the effective concentration of the library (>2nM) was accurately quantified by qPCR to ensure the quality of the library.
  3. Library Sequencing
    Different libraries were pooled and sequenced by Illumina Miseq/HiSeq according to the effective concentration and the required amount of target data. Four fluorescent labeled dNTPs, DNA polymerase, and adaptors were added to the flow cell for the amplification. When each sequence cluster extended and generated the complementary chain, the corresponding fluorescent signals were released and captured after each new dNTP was added. The optical signals were then transformed into sequencing peaks by professional software to obtain the sequence information of the fragments.
