    摘要: The present invention provides branched water-soluble polymers that allow two or more water-soluble polymers to be conjugated to another species. The branched polymers provide access to therapeutic agents that are conjugated at a single site to two or more water-soluble polymers. The branched polymers are based upon branch points that are simple branched alkyl structures, reactive side-chain amino acids and small peptides of reactive side-chain amino acids, and saccharides. Also provided is a method for preparing mono-disperse poly(ethylene glycol) of a well-defined and determinable molecular weight, and a method for the rational end-functionalization of poly(ethylene glycol). Conjugates of the branched water-soluble polymers with diverse species, e.g., peptides, lipids, glycolipids and small molecules are also provided.

    摘要: The present invention relates to mutants of human growth hormone, which contain newly introduced N-linked or O-linked glycosylation site(s), such that these recombinantly produced polypeptides have glycosylation patterns distinctly different from that of the naturally occurring human growth hormone. The polynucleotide coding sequences for the mutants, expression cassettes comprising the coding sequences, cells expressing the mutants, and methods for producing the mutants are also disclosed. Further disclosed are pharmaceutical compositions comprising the mutants and method for using the mutants.
