Cell surface proteins can be labeled using a specific protein binding molecule, such as an antibody conjugated to a Feature Barcode oligonucleotide. This protocol provides guidance for antibody-oligonucleotide conjugation and outlines cell surface protein labeling for use with Single Cell RNA sequencing protocols with Feature Barcoding technology. This protocol also provides guidance for enriching labeled cells using Fluorescence Activated Cell Sorting (FACS).

To design a custom conjugate oligonucleotide, use a sequence from the Feature Barcode inclusion list (CG000193). Please refer to the following article for details: How do I use the Feature Barcode Whitelist?
