Custom PhIP-Seq Service for Profiling of Autoantibodies

Rx Biosciences offers CustomPhage Immuno Precipitation Sequencing Service (PhIP Seq service) for profiling of autoantibodies in patients’ serum with phage display technology.  In this technology, a phage display library of predesigned oligopeptides of 50 to 90 amino acids is prepared in a modified T7 Select vector available with Rx biosciences.  The library is screened with a pool of antibodies isolated from a patient suffering from an autoimmune disorder. After hybridization, antibody-phage complexes are selectively captured by Protein A/G resin, and PCR amplified.  In the first round of PCR, the inserts of the library are amplified and purified.  In the second round of PCR, the indexes are attached to different samples created during the screening and sequenced upon MiSeq.  After sequencing, FastQ files are demultiplexed, aligned, and analyzed for the enrichment of patient-specific autoantibodies. PhIP-Seq experiments are useful in environmental exposures, allergies, ongoing or emerging autoimmune disorders, and responses to immunomodulatory therapies.
