The present invention provides assays utilizing SPR to detect protein-ligand interactions as well as compositions utilized is such assays.

The disclosure relates to the use of variants of C-type natriuretic peptide (CNP) to treat osteoarthritis, to ameliorate one or more symptoms of osteoarthritis, and to treat disorders having an osteoarthritis component.

The present invention relates to Atrial Natriuretic Peptide (ANP) polypeptides and methods of treatment with ANP polypeptides.

The present invention relates to Atrial Natriuretic Peptide (ANP) polypeptides and methods of treatment with ANP polypeptides.

The present invention relates to peptides with vasodilatory and/or diuretic functions. In particular, the invention relates to modifying key amino acid residues in natriuretic peptides to achieve different functions and properties. Accordingly the invention also includes modified natriuretic peptides. The invention also relates to the use of these peptides for regulating blood pressure-volume and/or treating a heart condition.

The present invention provides a conjugate comprising a hANP peptide bonded via a polyethylene glycol linker to a glycan attached to Asn297 of a Fc-containing molecule (N297 glycan), or a pharmaceutically acceptable salt thereof, a medicament comprising the same as an active ingredient, a method for producing the same, etc.

This disclosure provides methods to modify protein and peptide and antigen to treat disease such as pathogen infection, autoimmune diseases and cancer. The method involves increasing the molecular weight of the protein by connecting multiple peptide units with site specific conjugation to extend the in vivo half life. This disclosure also provides methods to construct activatable enzyme, which becomes active when they reach the treatment target, therefore provide higher specificity for treatment.
