Functional Protein Arrays

FPA Technology

In modern proteomics and systems biology, Functional Protein Array (FPA) technology has emerged as a powerful tool driving scientific innovation. By enabling high-throughput analysis of thousands of proteins, FPA helps researchers uncover protein functions, post-translational modifications, and molecular interactions-accelerating advances in disease diagnostics, drug development, and biomarker discovery.

FPA technology immobilizes thousands of purified proteins on a solid surface, analyzing their interactions with other biomolecules (e.g., small molecules, antibodies, DNA, RNA) to reveal biological functions. Unlike traditional analytical protein arrays, FPAs offer deeper insights into post-translational modifications (such as phosphorylation, ubiquitination, acetylation) and protein-protein interactions, providing robust technical support for disease mechanism studies and precision medicine.

Applications of Our FPA Services

Drug Screening and Target Discovery

FPA technology enables the rapid identification of target proteins that bind to specific drugs or small molecules, accelerating drug target validation and novel drug development. For example, FPA has been used to identify interactions between a chemical inhibitor and cell-cycle-related proteins, providing fresh insights for anti-cancer drug development. This technology offers the advantage of high-throughput screening, allowing numerous potential targets to be tested within a short period, which helps reduce experimental timelines and development costs.

Biomarker Discovery and Disease Diagnostics

FPA technology plays a pivotal role in identifying protein biomarkers linked to specific diseases, advancing precision medicine and personalized treatment. For example, in ovarian cancer research, FPAs were utilized to screen patient serum for antibody responses, leading to the identification of protein biomarkers for early diagnosis and prognostic evaluation. This technology offers the advantage of detecting low-abundance biomarkers while simultaneously analyzing multiple disease markers, delivering multidimensional diagnostic insights.

Post-Translational Modification (PTM) Analysis

FPAs efficiently detect post-translational modifications (PTMs), offering critical data for signal transduction research. A notable application of this technology is its use in analyzing phosphorylation events in yeast proteomes, where it helped identify novel phosphorylation substrates that provide valuable insights into signaling pathways and disease mechanisms. This technology allows for the simultaneous analysis of multiple PTMs, enabling a deeper exploration of their roles in cellular signaling.

Antibody and Immune Response Analysis

FPAs support the development of new vaccines and immunotherapies by analyzing antigen-antibody binding activities. In one application, FPAs were employed to evaluate antibody responses to candidate vaccines, helping to identify the most immunogenic antigens and optimize vaccine design. This technology efficiently assesses diverse antibody responses with high precision, facilitating detailed antibody characterization.
