Development of a Defined Cloning and Growth Factor Formulation for Murine Hybridomas

By Antibody Solutions Research Team on Jan 5, 2021 12:50:00 PM

Conditioned media from cultured cells have long been used to increase the cloning efficiency, growth rate and antibody secretion of hybridomas. The potential sources of conditioned media include cultured splenocytes, peritoneal macrophages, and macrophage, endothelial or fibroblast cell lines. The conditioned media from these cultures contain a variety of cytokines that act as growth factors for hybridomas. However, the constituents of conditioned media are largely undefined. Conditioned media may contain cell metabolites, cellular contaminants, and other undefined components that may interfere with the bio-analysis of hybridoma-derived antibodies.

A Rapid, High-Throughput Recombinant Antibody Expression System for Therapeutic Antibody Discovery and Validation

By Antibody Solutions Research Team on Dec 1, 2018 10:13:00 AM

Hybridoma cell lines have historically offered an efficient, low-cost means to produce large numbers of monoclonal antibodies. However, there are reasons that warrant recombinantly expressing an antibody at a preclinical, R&D stage. These reasons include the need to express antibodies from primary B cells, a surface display library, convert chimeric antibodies to fully human antibodies, humanization of rodent antibodies, and isotype switching. We have developed a recombinant expression system for drug discovery with the ability to express a large number of recombinant antibodies in a timely, cost-efficient manner.
