Hybridoma Sequencing Service

The acquisition of the monoclonal antibody gene sequence of hybridoma cells is the basis for recombinant antibodies and the development of antibody drugs. KMD Bioscience provides accurate and fast monoclonal antibody sequencing services to ensure that the antibody of interest can be accurately reconstituted before it enters downstream applications.

In the process of preparing recombinant antibodies, after customer supplies the hybridoma cells, there are two heavy chain and two light chain problems, which leads to the diversity of subsequent light and heavy chain pairing combinations, making the preparation of recombinant antibodies time-consuming and labor-intensive. Our scientists have proposed a very good solution. We designed a series of IgG primers for myeloma cells, combined with cell subcloning technology to finally obtain sequence information that is highly consistent with the target antibody.
