Bio-Plex Multiplex Assays

Many instruments offer multiplexing capability for biomarker measurements. But to handle and make sense of the huge amount of multiplex data requires sophisticated software like Bio-Plex Data Pro, which simplifies organization, import, sorting and visualization of data, and performing calculations and statistical analyses.

The T-helper cell (Th17) pathway has been implicated in several autoimmune diseases and in cancer. New magnetic bead–based assays have been developed for several biomarkers in this pathway. The performance characteristics of these assays are evaluated from data on intra- and inter-assay precision, standard curve recovery, cross reactivity, and linearity of dilution.

Dr Hunseok Lee of Seoul National University explains why it was advantageous for him to use the Bio-Plex system to measure cytokine levels in patients administered with the new cancer vaccine that his laboratory has developed.

Dr Hunseok Lee has known since childhood that he wanted to grow up to become a scientist. “You get to wear white gowns, look through a microscope at various substances so small they can’t be seen by the naked eye — those things were very attractive to me when I was young,” says Lee. But the realities of putting research into practice and translating ideas into experiments have proven far more strenuous than the young Lee anticipated.

The Bio-Plex Pro human Th17 cytokine panel is a unique blend of magnetic bead-based multiplex immunoassays for the robust and reproducible measurement of 15+1 soluble proteins involved in the T-helper cell type 17 immune response pathway.

Bio-Plex Pro™ Human Cancer Biomarker Panel 1 is a unique blend of magnetic bead-based assays designed to meet the needs of the most discerning preclinical and clinical researchers.

This report demonstrates that the TC10 automated cell counter is a suitable alternative to the Coulter Counter and hemocytometer for the preparation of custom Bio-Plex assays.

Watch how the Bio-Plex® suspension array system has contributed to research findings in Dr Francis Spinale and Dr Steven Kornblau’s laboratories that have the potential to impact screening and treatment of disease.

Identifying Cardiac Defect–Related Protein SignaturesAugust 15, 2011 “The first opportunity I had to lay my hand on a human heart I knew that was that — I knew that I wanted to know how the heart works, but more importantly, how it doesn’t work,” says Dr Francis Spinale, describing his inspiration to both research and treat cardiac disease. Using the Bio-Plex® suspension array system, researchers in his laboratory are discovering protein signatures that have the potential to inform decision strategies in cardiac patient treatment.

Dr. Steven Kornblau has been on faculty at MD Anderson Cancer Center in Houston, Texas, for 20 years, where he divides his time between research into further understanding leukemia disease states, and a clinical practice where he treats a small number of patients with the disease. Recently, his laboratory used the Bio-Plex® suspension array system to discover how cytokine and chemokine profiles alone can be prognostic for patients with the disease, and therefore have to potential to assist development of personalized treatments.
