The growth hormone with high biological activity modified by the double-stranded polyethylene glycol at a single site and the preparation method thereof are provided. The PEGylated growth hormone has a higher biological activity and a longer half-life than the unmodified growth hormone. The composition comprising the PEGylated growth hormone is useful in the treatment of the growth or development disorder such as growth hormone deficiency, Turner syndrome etc.

Disclosed herein are immunoglobulin fusion proteins comprising a first antibody region, a first therapeutic agent, and a first connecting peptide; wherein the first therapeutic agent is attached to the first antibody region by the connecting peptide; and wherein the connecting peptide does not comprise a region having beta strand secondary structure. The connecting peptide may comprise an extender peptide. The extender peptide may have an alpha helical secondary structure. The connecting peptide may comprise a linker peptide. The linker peptide may not comprise any secondary structure. Also disclosed herein are compositions comprising the immunoglobulin fusion proteins and methods for using the immunoglobulin fusion proteins for the treatment or prevention of a disease or condition in a subject.

Transgenic microalgae expressing at least one exogenous biologically active protein. The protein-expressing microalgae are used for the oral delivery of the biologically active protein to the target organism in its intact and functional form. The exogenous protein, expressed in algae, is characterized by being biologically active, exerting at least one specific activity having a beneficial effect on the subject consuming the algae. The transgenic microalgae are used as animal food for aquatic or land animals welfare or as food supplement for human healthcare.
