eBioscience, an Affymetrix (Nasdaq:AFFX) business, announces the availability of PrimeFlow™ RNA Assay, the first and only flow cytometry assay capable of simultaneous detection of RNA and protein within millions of cells at single-cell resolution. Current flow cytometry applications are limited to antibody-based interrogation of cell surface and intracellular proteins. With the novel PrimeFlow assay, researchers can now incorporate the simultaneous analysis of RNA transcripts and proteins to elevate their understanding of single-cell dynamics.

“Single-cell analysis is a rapidly growing field in biomedical research that yields an unprecedented level of information,” said Filippos Porichis, PhD, Director of the Ragon Institute of MGH, MIT and Harvard’s International Programs and first author of a newly published Nature Communications paper citing the use of RNA transcript with flow cytometry. “PrimeFlow RNA Assay enables high throughput detection of RNA and protein expression; therefore, it can be used to characterize, mechanistically and phenotypically, co-expression of RNAs with the functional proteins at the single-cell level. This assay, with a user-friendly protocol that has many similarities with standard antibody-staining procedures and data acquisition of flow cytometry, is an invaluable tool for any immunology lab performing translational research.”

“The major advantage of this technology is the ability to detect, with high sensitivity, mRNAs for which flow cytometry antibodies against the corresponding proteins perform poorly or are not available,” adds Dr. Daniel Kaufmann, Research and Clinical Associate Professor, Dept. of Medicine, University of Montreal. “Furthermore, the capability to directly measure non-coding RNAs, whose critical functional roles are increasingly recognized, in a heterogeneous cell population has vast potential applications in cell biology.”

“Single-cell gene expression assays, such as PrimeFlow RNA Assay, showcase one of the many exciting opportunities we have for integrating cell analysis and genomics, which open up new avenues for innovation and growth,” said Frank Witney, CEO and President of Affymetrix. “PrimeFlow RNA Assay represents the capabilities and expertise of eBioscience and Affymetrix brought together to enable the scientific community to advance the understanding and application of biology for a better world.”

Find the best labware and lab supplies in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays. Find the best flow cytometers, cell counters and cell sorters in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates. Find the best protein purification equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Protein DetectionProtein detection techniques are essential for understanding protein expression, localization, and function. Methods such as western blotting, ELISA, and mass spectrometry are commonly used in research and diagnostics. Browse our peer-reviewed product directory to find the best tools for protein detection, compare products, check reviews, and get pricing directly from manufacturers.
