Ultra-High Throughput Single Cell Analysis of Proteins and RNAs by Split-pool Synthesis

We report a method enabling simultaneous, ultra-high throughput single-cell-barcoding, of millions of cells for targeted single cell analysis of proteins and RNAs. This method termed Quantum Barcoding (QBC) circumvents the need to isolate single cells by building cell-specific oligo barcodes dynamically within each cell. With minimal instrumentation (four 96-well plates and a multichannel pipette) cell-specific codes are added to each tagged molecule within cells. This is accomplished through sequential rounds of the well-established process of classic “split-pool synthesis”. We demonstrate the utility of this currently research use only technology in multiple model systems. Analysis of various cell types by the QBC single-cell analysis technology
