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 bio-similars. KMD Bioscience provides monoclonal antibody sequencing services with accuracy and speed. For your convenience and let you rest assured, KMD Bioscience follows strict rules and is conscientious and rigorous in the implementation of our services, ensuring that the antibody of interest can be accurately reconstituted before it enters downstream applications.

In the process of preparing recombinant antibodies, after the 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. But KMD Bioscience knows how valuable your time is, and our scientific team has finally found a 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.


Service Contents:
