Seranova Bio's REAP platform highlights new functional autoantibodies in autoimmune diseases APECED and Lupus
Autoantibodies that recognize extracellular proteins (the “exoproteome”) exert potent biological effects but have proven challenging to detect with existing screening technologies.
Here, we developed Rapid Extracellular Antigen Profiling (REAP) as a technique for comprehensive, high-throughput discovery of exoproteome-targeting autoantibodies. With REAP, patient samples are applied to a genetically-barcoded library containing 2,688 human extracellular proteins displayed on the surface of yeast. Antibody-coated cells are isolated by magnetic selection and deep sequencing of their barcodes is used to identify the displayed antigens.
