The goal of the Common Fund’s Protein Capture Reagents program is to develop a community resource of renewable, high-quality protein capture reagents, such as antibodies, with a focus on the creation of transcription factor reagents and testing next generation capture technologies. The program has developed new resources and tools to understand the critical role the multitude of cellular proteins play in development, health, and disease. These resources will support a wide-range of research and clinical applications by enabling the isolation and tracking of proteins of interest.
The program generated an array of monoclonal antibodies to transcription factor targets in addition to a host of recombinant antibodies. The Common Fund has provided funding to experts in the field of transcription factors to validate the usefulness of these antibodies. Using a variety of different methods, ranging from chromatin immunoprecipitation (ChIP) to microscopy studies, approximately 40 antibodies have already been identified as highly effective tools for biological studies. As more validation studies are completed, it is anticipated this number will increase. These antibodies are publicly available for purchase and can be located through the PCRP Data Portal. A 2016 commentary paper published in Nature Methods outlines the accomplishments of the program.
A renewable resource of protein capture reagents – specifically designed to meet research and clinical demands ranging from protein isolation and high-throughput assays to diagnostics and biomarker development – is needed to advance the field of proteomics and fuel biomedical research. To have the maximum benefit, such reagents would need to be high quality, affordable, reliable monoclonal antibodies and other reagents that can collectively target the range of possible proteins within cells and tissues. But what do these reagents look like and how can they be developed, optimized and scaled for use in large-scale proteomics research and clinical applications? The Common Fund Protein Capture Reagents program sought to address these questions and establish a “protein capture” resource of reagents for the biomedical community. See: Program Highlights for more information and ProteinCapture.org for the reagents that are currently available.
