NIR RPPA Detection Together with Dynamic Range Extension (XDR) Function in the Innoscan 710-IR Scanner Makes RPPA Detection Cheaper By 90 Percent
12 Nov 2014Reverse Phase Protein Arrays (RPPA) also named cell lysate arrays have been shown to be useful tools for biomarker evaluation in large patient cohort. One of the challenges of this technology is the dynamic range, since biomarker expression levels can vary from fento-molar (fM) to micro-molar (μM) concentration in the same cohort. This application note demonstrates how, using the dynamic range extension (XDR) function in the InnoScan 710-IR scanner, RPPA costs are dramatically diminished when switching from colorimetric to fluorescence detection.

Microarray AnalysisMicroarrays, also known as biochips, are used for the detection and analysis of multiple genes, proteins, antibodies, or biomarkers on a single microchip. This can reveal information on protein or gene expression, single nucleotide polymorphism (SNP), copy number variation (CNV), epigenetics and patient health in clinical diagnostic tests. Discover a range of microarray scanners and prefabricated antibody, protein, RNA and DNA microarrays for your analysis or consider creating your own custom microarrays with a microarray printer.

The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Biomarker DiscoveryClinical biomarkers refer to substances related to known medical conditions that can be accurately measured <i>in vitro</i>. Biomarkers can be used to diagnose presence of a disease and indicate disease severity. The discovery of new biomarkers is incredibly valuable in the field of diagnostics.RPPA
