Our Comprehensive Conjugation Strategy for Glycan Linking to Coat Protein pVIII for Client

CD BioGlyco has developed the LiGA platform to provide clients with more comprehensive glycan interaction analysis services. In the process of LiGA Construction, attaching the glycan to the coat protein pVIII of M13 bacteriophage is a very critical step. Since there is no natural glycosylation for the M13 bacteriophage, the glycan required for the experiment needs to be attached to the bacteriophage by coupling. We use chemical or enzymatic coupling to perform the ligation, thus producing a multivalent Display of the Glycan.

• Glycan Chemical Conjugation to Coat Protein pVIII

Glycan is chemically reactive with the reactive functional groups on pVIII. For this reason, we use chemical conjugation to attach the glycan to pVIII, forming a covalent bond between them. Depending on the specific reactive groups, we use different chemical conjugation methods, such as strain-promoted azido alkyne cycloaddition (SPAAC), Cu-activated azido alkyne cycloaddition (CuAAC), and so on.

• Glycan Enzymatic Conjugation to Coat Protein pVIII

Enzymatic conjugation is also an effective method to link glycans and pVIII. Under appropriate reaction conditions, we employ specific enzymes to conjugate pVIII and glycans.

We choose the appropriate conjugation strategy based on the density and structure of the glycan on pVIII. During the conjugation process, we consider the effects of experimental conditions on the stability and functionality of the glycan and pVIII. By optimizing and adjusting the experimental conditions and conjugation method, we finally achieve the ideal density of the glycan. During the experiment, we also adjust the experimental process and introduce modifications to meet the specific research needs of our clients. Finally, we verify the binding affinity and specificity of the conjugate by enzyme-linked immunosorbent assay (ELISA).
