• • How PhIP-Seq Works for Antibody Repertoire Profiling

  PhIP-Seq antibody repertoire profiling links antibody binding with next-generation sequencing. Antibody-containing samples are exposed to a phage display peptide library. Antibodies pull down phage clones that display recognized peptides, and sequencing reads identify which peptides were enriched.

• • PhIP-Seq Characterization of Serum Antibodies Using Oligonucleotide-Encoded Peptidomes

  Phage immunoprecipitation sequencing, widely known as PhIP-Seq, was developed for this type of discovery challenge. By combining phage-displayed peptide libraries with DNA sequencing, PhIP-Seq can characterize antibody binding patterns in serum or plasma at peptide-level resolution.

• • Identifying Disease Biomarkers with Phage Immunoprecipitation Sequencing

  Phage immunoprecipitation sequencing addresses this problem by combining phage display peptide libraries with antibody capture and next-generation sequencing. Antibody-containing samples are incubated with a library of displayed peptides.

• • Guide to PHIP-Seq: Experimental Design, Workflow, and Execution Standards

  PHIP-Seq experimental design often determines whether an antibody profiling project produces interpretable candidates or a difficult list of enriched peptides. In autoimmune disease research, infectious disease serology, vaccine response studies, and biomarker discovery, researchers may have valuable serum or plasma samples but limited tolerance for repeat experiments.
