Empowering Glyco-engineered Cells, One Pathway at a Time

Utilizing glycoengineering to construct cells is an efficient and flexible tool. Depending on the glycosylation pathway, CD BioGlyco provides various types of Glycoengineered Cell Constructs for clients. For example, GSL pathway-based glycan engineering cell construction.

• We utilize the HEK293 cell line as a framework to construct a cell-based glycan display, based on the fact that HEK293 cells have all types of lipid and protein glycosylation capabilities, pathway-specific extensions, and branching features. Moreover, the glycan features produced by GSL are not restricted in HEK293 cells.
• We utilize glycosyltransferase-based clustered regularly interspaced short palindromic repeats (CRISPR) / Cas9 gene editing tools to design and analyze the glycosylation capacity of cell lines. Homozygous cells with specific glycosylation features are constructed by altering glycan complexity branching through knockout (KO) and knock-in (KI) of glycosyltransferase genes.
• We provide predictions of the effects of individual genes on glycan structural features based on the GSL pathway (combinatorial CRISPR/Cas9 KO targeting to control glycosphingolipids results in allelopathic cells differentially displaying glycan features on one or more of these glycoconjugates).

Furthermore, we use a combination of gene editing approaches to eliminate and introduce the ability of cells to glycosylate de novo and develop sub-libraries of stably engineered homozygous cells. On the other hand, we classify glycosyltransferase genes into regulated and non-regulated based on transcriptomic data to further provide differentially regulated glycosylation steps and pathways.
