Monoclonal antibodies are the fastest-growing class of therapeutic agents with success in treating a wide range of diseases such as cancer, cardiovascular disease, autoimmune disorders and infectious disease. Most therapeutic antibody candidates are initially generated from mouse hybridomas or primary B cell clones after antigen immunization. In the antibody discovery workflow, primary screens identify clones with specific attributes that are assessed for a variety of critical parameters such as IgG isotyping, antibody quantification, and cell health metrics, which is vital information for lead molecule generation.
Quantification of mouse antibody from cell culture supernatant is traditionally assessed using enzyme-linked immunosorbent assay (ELISA). Additionally, separate IgG isotyping and cell count/health assays are performed to facilitate and optimize cloning of antibody variable regions into the proper expression vector. To overcome limitations of these traditional assays, we developed a high throughput, multiplexed assay that expedites antibody discovery, identifying optimal clones for downstream processes.
This is a multiplex competition assay which uses isotype-specific beads in the same well to capture four mouse IgG isotypes (IgG1, 2a, 2b, 3) from the sample. This biochemistry achieves a wide dynamic range, reduces the need for sample dilution and eliminates wash steps. Our data shows that critical mouse antibody parameters can be assessed using a single, high throughput multiplex assay. The high-content data generated by this assay simplifies the antibody discovery workflow and reduces the time to make actionable decisions.
