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

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

Review of Mujawar et al Analytical Chemistry – Distribution of Biomolecules in Porous Nitrocellulose Films

An interesting paper in (Analytical Chemistry) describes the use of confocal fluorescence section imaging to analyze protein distribution in microarray spots on nitrocellulose film slides. By scanning and imaging through the Z dimension of a printed spot of fluor labeled protein, a 3-dimensional quantitation of fluorophore density in the films was obtained, showing that commercial … 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

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

Optimize Your Protein Array with Specially Formulated Arraying Buffer

The buffer used for spotting proteins for protein arrays is a critical factor in obtaining reliable and consistent results. Most important impact is on protein aggregation, which can affect spot morphology, and protein binding to the substrate. Grace Bio-Labs has developed a Protein Arraying Buffer designed to work with our ONCYTE® porous nitrocellulose film slides for optimal … Continued

High Density Protein Arrays for Antibody Validation

A recent paper in BMC Biotechnology by D. Ma et. al of Origene describes the use of high density protein arrays to test the specificity, or lack thereof, for antibodies used for immunoassay diagnostics. The antibody 8F1 is commonly used in immunohistochemistry assays to detect ERCC1 protein, a biomarker for testing the efficacy of cisplatin-based chemotherapy used in non-small lung … Continued
