The generation of monoclonal antibodies (mAb) of desired specificity to cell surface antigens can serve as a valuable tool to study protein expression and function. However, traditional approaches to mAb generation usually involve large-scale protein purification and intensive screening, and may not result in mAb specificities to the native protein of interest. We describe a simple, inexpensive, high-throughput method for the generation and screening of hybridomas secreting mAb specific for cell surface receptors. Intact reporter cells expressing a CD3ζ-fusion receptor of the protein of interest are plated in 96-well arrays of captured, plate-bound hybridoma supernatants. A mAb to the protein of interest generates a signal leading to reporter-cell expression of β-galactosidase, and enzyme activity can be screened in a single day using a non-radioactive substrate. Importantly, a single cell line can be used for immunization, screening, semi-quantitative affinity comparisons, and subsequent screening for physiological ligand expression, if the protein of interest is a receptor. We describe an application of this approach to generate mAb specific for a protein of previously unknown expression and undocumented function.
