Cell surface proteoglycan that bears heparan sulfate. Biological Activity: Fully biologically active when compared to standard. The specific activity is determined by binding ability in a functional ELISA. Immobilized rHuSYND4 at 500ng/ml (100ul/well) can bind rHubFGF with a linear range of 0.1-10ng/ml.
