Applications of Protein Microarrays for Biomarker Discovery.

In a recent paper published in the Journal of Neuroinflammation the immune response associated with elevated intermittent ocular hypertension has been evaluated.  An antigen microarray assay was performed with ten different antigens spotted on ONCYTE®  nitrocellulose film slides and used to probe serum from an intermittent ocular hypertension animal model. High Intraocular pressure is a main risk … Continued

Multiplexed ONCYTE Protein microarrays Used for Infectious Disease Immunogen Discovery

First, in an interesting Shistotosomiasis study, Gaze, et al, employ protein microarrays in a longitudinal immunomics study for vaccine antigen discovery (1).  Schistosomiasis is a pervasive disease affecting 200 million people a year and traditional drug treatments are ineffective due to re-infection, drug expense, and parasite drug resistance. Non-sterile immunity does develop over long periods of … Continued

Sensitive and Accurate Multi-Color RPPA Using Grace Bio-Labs ArrayCAM Protein Microarray System

Introduction Profiling sets of multiple protein markers and signaling pathways is becoming the standard method for biomarker discovery, accurate disease diagnosis, and monitoring of therapeutic response. Low-cost, high throughput multiplexed assay platforms that can provide specific, sensitive, and reproducible measurements, featuring reliable and robust assay controls along with easy to use methodologies will yield increased … Continued

Improved Classification of Influenza Infection, Future Susceptibility and Pandemic Epidmiology using ONCYTE Porous Nitrocellulose Film Microarrays

An interesting paper furthering the expansion of infectious disease serological applications using ONCYTE porous nitrocellulose film slides was described by researchers out of the Netherlands for classifying influenza infections and susceptibility to future infections. Microarrays printed on ONCYTE AVID film slides used purified recombinant influenza virus hemagglutinin antigens (HA1) from various subtypes (H1, H2, H3, … Continued

Quantum Nanocrystal (QNC) Detection and ONCYTE AVID Porous Nitrocellulose Results in Improved RPPA Quantitation and Dynamic Range

ONCYTE porous nitrocellulose (PNC) film slides are a 3-D substrate very well suited for protein microarrays due to its high binding capacity and ability to retain proteins’ conformation and antigenic sites. PNC slides have proven extremely valuable for Reverse-Phase Protein Arrays (RPPAs) in the field of cancer research.In recent years, interest in further improving the … Continued

Validation of a Novel One-Step Tissue Fixation Chemistry That Preserves Phosphoproteins and Histomorphology

  George Mason University Poster Presentation for the National Cancer Institute’s 15th Annual IMAT Principle Investigators Meeting, November 13-15, 2014. Unmet need: A significant and underappreciated issue is the fact that excised tissue is alive and reacting to ex vivo stress [1]. During this “cold ischemia time” cells within the tissue react and adapt to the absence … Continued

Sensitive Detection of Total Protein on RPPA using Fast Green

Reverse phase protein arrays (RPPA) are designed for sensitive quantitation of a target protein in a very small sample of tissue lysate, and multiplex analysis of many samples in one experiment. This technology holds great promise for the identification and analysis of critical biomarkers for disease states in patient samples and for high-throughput drug screening … Continued

Antigen Discovery – Pioneer in High Throughput Biomarker Discovery

Antigen Discovery Inc.’s protein microarrays allow for highly multiplexed assays the generate hundreds, thousands and tens of thousands data points for each sample tested. Antigen Discovery Inc., our collaborators and our customers have leveraged this technology to peer into the complex intricacies of the immune response to disease generating over 80 peer-reviewed research articles in … Continued

From Western Blot to Protein Array with Super G Blocking Buffer

Results obtained from Western blots can be highly variable and dependent not only on the specific antigen/antibody pairs used, but also on other reagents in the protocol such as blocking buffer. Not surprisingly, no one “universal” blocking reagent works well with all proteins. Thus choice of blocking reagent should be assessed for optimal results and having … Continued

View Your Proteins in 3-D!

Protein microarray technology has progressed significantly and, although new microarray surface chemistries continue to be developed and marketed, porous nitrocellulose has remained the predominant immobilization surface for protein microarray applications due to its many functional advantages.  The 3-dimensional structure of nitrocellulose film slides offers a considerably higher surface area for protein binding compared to conventional … Continued

Print Macroarrays with ProPlate

ProPlate® Chambers for Macroarray Printing Many laboratories desire the benefits of utilizing microarray technology in their field of interest but do not have access to microarray printing equipment or cannot justify the expense of dedicated print runs for lower throughput experiments.  In many cases where highly multiplexed assays are not a necessity or during early-phase … Continued
