  • Publication number: 20140315276
    Abstract: Methods are provided for a one step synthesis of polypeptide polymers or co-polymers. The polymers or co-polymers can be linear or branched. In the methods of the invention, the coding sequence for the polypeptide(s) to be polymerized is altered by introducing one or more codons for an nonnatural amino acid, which coding sequence is then utilized to produce the cognate polypeptide. The nonnatural amino acids are selected to be reactive with each other in a bioorthogonal reaction, and are combined in a conjugation reaction with the desired components of the polymer.

  • Patent number: 8859734
    Abstract: The embodiments of the invention relate to a method for the introduction of a labeling structure such as a fluorescent molecules or a Raman tags to a compound. Imidazole functionalized resins or polymers are used to selectively immobilize phosphocompounds without protecting the carboxylic groups. Relying on the pKa difference between amines and hydrazides and carrying out the reaction in a slightly acidic buffer, all of the amines are protected by protonation while the hydrazides react with the phosphate imidazolide to form a phosphoramidate bond.
