emtek 2113 Conbercept is a genetically engineered homodimeric protein for the treatment of wet age-related macular degeneration (wet AMD) that functions by blocking VEGF-family proteins.Its huge, highly variable architecture makes characterization and development of a functional assay difficult.In this study, the primary structure, number of disulfide linkages and glycosylation state of conbercept read more were characterized by high-performance liquid chromatography, mass spectrometry, and capillary electrophoresis.

Molecular modeling was then applied to obtain the spatial structural model of the conbercept-VEGF-A complex, and to study its inter-atomic interactions and dynamic behavior.This work was incorporated into a platform useful for studying the structure of conbercept and its ligand binding functions.
