Abstract

Disclosed herein include systems, methods, compositions, and kits for sample identification. A sample indexing composition can comprise, for example, a protein binding reagent associated with a sample indexing oligonucleotide. Different sample indexing compositions can include sample indexing oligonucleotides with different sequences. Sample origin of cells can be identified based on the sequences of the sample indexing oligonucleotides. Sample indexing oligonucleotides can be barcoded using barcoded and lengthened using daisy-chaining primers.
