Cell Surface-based Enzymatic Conjugation Service

The understanding and manipulation of the cell surface are important topics for fundamental studies of cell behavior and translational research on novel biotechnical applications and therapeutic development. As an industry-leading cell surface engineering services provider, Creative Biolabs has accumulated rich precious experience in practice. With extensive experience and strong foundations, we are capable of providing high-quality cell surface-based enzymatic conjugation services.

Introduction of Cell Surface-based Enzymatic Conjugation

Incorporation of unnatural moieties into the cell surfaces can be achieved by incubating the cells with exogenous enzymes in proper conditions, which can catalyze the enzymatic reaction on the cell surfaces in the presence of the necessary substrates. The enzymes either can recognize the naturally existing substrate on the cell surface and transform it into an unnatural functional group or can recognize a specific sequence introduced by traditional molecular biology methods. Due to the mild reaction conditions which are generally compatible with live cells, covalent bond formation, and substrate specificity, enzyme-mediated engineering of live cell surface provides an excellent opportunity to load a cargo moiety including peptides, proteins, and nanoparticles to the cell surface.
