Shared resources

One of the goals of the Chemistry and Biology of Heparan Sulfate PEG is to provide the broader scientific community with resources to assist in the application of glycosciences to heart, lung and blood research.

We encourage glycoscience researchers to make use of the resources offered by the laboratories involved in the Chemistry and Biology of Heparan Sulfate PEG.
