Single-cell multi-omics analysis has emerged as a crucial tool in modern biology due to its capacity to uncover the intricate molecular heterogeneity within individual cells. Glycan structural diversity on the cell surface creates a "cell signature" that varies by cell type and state. However, single-cell glycan analysis remains a challenge. This protocol presents a series of techniques and procedures that enable the simultaneous measurements of glycan and RNA at the single-cell level via DNA-barcoded lectin-based sequencing (scGR-seq). The techniques include (1) the preparation of DNA-barcoded lectins, (2) a step-by-step protocol for single-cell glycan/RNA sequencing, and (3) a data analysis approach for the integration of glycan and RNA data. © 2023 Wiley Periodicals LLC.

D002462	Cell Membrane	The lipid- and protein-containing, selectively permeable membrane that surrounds the cytoplasm in prokaryotic and eukaryotic cells.	Plasma Membrane,Cytoplasmic Membrane,Cell Membranes,Cytoplasmic Membranes,Membrane, Cell,Membrane, Cytoplasmic,Membrane, Plasma,Membranes, Cell,Membranes, Cytoplasmic,Membranes, Plasma,Plasma Membranes
D012313	RNA	A polynucleotide consisting essentially of chains with a repeating backbone of phosphate and ribose units to which nitrogenous bases are attached. RNA is unique among biological macromolecules in that it can encode genetic information, serve as an abundant structural component of cells, and also possesses catalytic activity.

D037102	Lectins	Proteins that share the common characteristic of binding to carbohydrates. Some ANTIBODIES and carbohydrate-metabolizing proteins (ENZYMES) also bind to carbohydrates, however they are not considered lectins. PLANT LECTINS are carbohydrate-binding proteins that have been primarily identified by their hemagglutinating activity (HEMAGGLUTININS). However, a variety of lectins occur in animal species where they serve diverse array of functions through specific carbohydrate recognition.
