Two capillary based immunoassay systems have been established in the Collaborative Protein Technology Resource (CPTR) core. First, the Nano(fluidic)Pro(teomics) technology is a capillary-based isoelectric-focusing(IEF) immunoassay system, which employs high-resolution IEF separation of proteins by charge followed by target-specific immunoprobing to detect and quantify multiple protein phosphorylation isoforms. Nanopro assesses protein phosphorylation both qualitatively and quantitatively, and provides more specific and unique information on the activation status of signaling molecules that are not readily assessed by traditional western blotting. Good reproducibility has been obtained with the NanoPro system. Second, the Simple Western system is a fully automated, gel free, blot free western system. All steps following sample preparation are fully automated, including sample loading, size-based protein separation, immunoprobing, washing, detection and data analysis. The system greatly minimizes the variability caused by manual processes in traditional western, and highly quantitative data and excellent reproducibility have been obtained with the system. A panel of capillary immunoassays has been developed and validated in our core, covering major key signal pathways from receptor activation, down-stream signaling transduction, transcriptional regulation, cell cycle control to apoptosis etc.. Through collaborations with investigators from different branches/laboratories of NIH, we have successfully applied the technology to profile cell signaling events in a variety of projects from basic research to clinical studies (see below the list of conference presentations and manuscripts in preparation). The small required sample size and comprehensive signaling molecule characterization, plus highly quantative data and good assay reproducibility of the technology are creating new opportunities for pharmacodynamic biomarker assessment in clinical studies. Assays and protocols have been developed and used to evaluate target therapy responses in peripheral blood mononuclear cells (PMBCs), CD138+ multiple myeloma cells from bone marrow aspirates and solid tumors in multiple clinical trial samples. We have also established a close working relationship with the technology developer, ProteinSimple for continuing improvement of the assay systems to be more robust and reliable, which have resulted in enhanced assay performance and readiness for clinical applications, and as well as making our core a leader in these novel technologies.
