Kode Technology – a universal cell surface glycan modification technology

Summary: Cells are highly decorated with glycans (carbohydrates) and this complex and dominating coating on cells, which also carries the glycan blood group antigens, is critically important to immunology and many related clinical practices such as transfusion, transplantation and immunotherapy. The ability to modify this glycan coat is difficult to achieve with standard techniques like molecular biology or direct chemical ligation, particularly as glycosylation is probably the most complex secondary gene event in a cell. However, the natural ability of lipid-linked structures to self-insert and hydrophobically anchor into cell membranes opened up the opportunity to develop synthetic Function-Spacer-Lipid technology for cell surface modification. From this glycan modification aspect Kode Technology has been used to add glycan related blood group antigens such as ABO, Lewis, P, FORS, as well as sialooligosaccharides and hyaluronic acid onto cells to study immunology and cell glycosylation and more recently as a potential immuno-oncotherapeutic therapy.

Rapid one-step biotinylation of biological and non-biological surfaces

Summary: We describe a rapid one-step method to biotinylate virtually any biological or non-biological surface. Contacting a solution of biotin-spacer-lipid constructs with a surface will form a coating within seconds on non-biological surfaces or within minutes on most biological membranes including membrane viruses. The resultant biotinylated surface can then be used to interact with avidinylated conjugates, beads, vesicles, surfaces or cells.
