Fluidigm Corporation, a leader in mass cytometry and microfluidics technologies, today announced the introduction of a REAP-seq (RNA expression and protein sequencing) protocol for use with the C1™ system. C1 REAP-seq is a powerful multi-omic single-cell application that enables deep characterization of unique cellular subtypes and functional states by measuring the expression of both cellular proteins and RNAs. Capable of pairing with functional imaging assays that measure differences in cell size, morphology or phenotype within the clear C1 microfluidic cell chambers, C1 REAP-seq represents a significant step forward in multi-omic analysis for basic and translational research.
“C1 REAP-seq is a powerful new protocol that will enable researchers to gain greater understanding of the underlying mechanisms of cancer progression and immune response,” said Carsten Krieg, PhD, Single Cell Analytics LLC. “Providing an unprecedented view into the dynamics of protein expression at single-cell resolution, C1 REAP-seq offers a new paradigm to accelerate the identification of actionable biomarkers and drug targets.”
C1 REAP-seq was developed in collaboration with Merck for co-detection of both cellular protein and RNA using microfluidics technology. Utilizing the REAP-seq technology developed and published in Nature Biotechnology by Merck scientists (Peterson et al., 2017), C1 REAP-seq allows simultaneous analysis of up to 82 different proteins and more than 20,000 genes per cell in a single workflow. Cellular proteins are identified using third-party antibodies conjugated to unique 15-base pair barcodes that are detected by next-generation sequencing. The application is ideal for deep characterization of hundreds to thousands of cells downstream of cell atlasing studies, enabling the simultaneous detection of more cell surface protein markers than traditional cytometry approaches alone.
