The invention provides monofunctional, bifunctional, and multifunctional PEGs and related polymers having a terminal thioester moiety capable of specifically conjugating to the α-amine of a polypeptide having a cysteine or histidine residue at ... 07/27/06 - 20060167233 - One-step reduction and alkylation of proteins The present invention relates generally to the field of analyzing proteins and more specifically to the reduction and alkylation of protein samples during protein analysis. A novel composition and method for reducing and alkylating proteins is disclosed. A novel reagent including a combination of a volatile reducing agent, a volatile ... 06/15/06 - 20060128948 - Biological low-molecular-weight derivatives The crosslinking agents and condensing agents that have been employed in biological adhesives and in treating medical devices such as cardiac valves are non-natural compounds synthesized artificially. Thus, they are not metabolized in vivo and exhibit toxicity to living bodies. These compounds are thus used only in a restricted amount ... 03/09/06 - 20060052586 - Process for preparation of mixtures of polypeptides using purified hydrobromic acid The subject invention provides an improved process for obtaining a mixture of polypeptides having nonuniform amino acid sequences, where each polypeptide consists essentially of alanine, glutamic acid, tyrosine and lysine where the resulting mixture of polypeptides comprises less than 0.3% brominated tyrosine and less than 1000 ppm metal ion impurities. ... 01/12/06 - 20060009623 - C-terminal attachment of ligands to proteins for immobilization onto a support The present invention provides methods of immobilizing proteins onto a support, using a cellular expression system or a cell-free expression system, to attach a ligand to the C-terminus of the protein, by an intein-mediated or a puromycin-mediated approach. A method for improving the efficiency of intein-mediated ligand attachment is also ... 01/12/06 - 20060009622 - Conjugates of therapeutic or cytotoxic agents and biologically active peptides The invention features conjugates of therapeutic or cytotoxic agents and biologically active peptides and methods of use thereof. ... ### FreshPatents.com Support |
