Cell surface proteins can be labeled using a specific protein binding molecule, such as an antibody conjugated to a Feature Barcode oligonucleotide. This protocol outlines cell surface protein labeling for use with Chromium Fixed RNA Profiling with Feature Barcode technology for Cell Surface Protein. This protocol also provides guidance for enriching labeled cells using Fluorescence Activated Cell Sorting (FACS). Please note: This demonstrated protocol is only compatible with Singleplexed Samples.
Optional cell surface protein labeling must be completed prior to sample fixation.
