发明人：FONG DODD W; HOOTS JOHN E
权利人:NALCO CHEMICAL CO
摘要:A polymer having pendant fluorescent groups is prepared by (trans)amidation of a preformed polymer by reaction with an amine-containing organic fluorescent composition of the Formula III Formula III wherein one of R5 and R6 may be hydrogen, and wherein within at least one of R5 and R6, or within R5 and R6 taken together, is an organic fluorescent group wherein the organic fluorescent group includes a polynuclear aromatic ring system. A degree of (trans)amidation derivatization of the polymer is accomplished by heating the admixture of polymer and fluorescent agent for a sufficient period of time. A second amine-containing post-polymerization derivatization agent other than the organic fluorescent composition of Formula III is added to the admixture or to at least a portion of the reaction product of the (trans)amidation derivatization, and is heated therewith to accomplish a degree of sequential or simultaneous post-polymerization derivatization with the second amine-containing post-polymerization derivatization agent.

标 题 :Rapid synthesis and analysis of carbohydrates
发明人：MAZID M ABDUL; KLOCK JOHN C
权利人:GLYKO INC
摘要:The subject invention provides novel methods and apparatus for synthesizing carbohydrates of a desired structure. The subject synthesis methods include using carbohydrage-modifying enzymes to perform individual synthesis reaction steps and electrophoresis to purify the reaction products for possible further use as substrates in additional synthesis reactions. The subject invention also provides novel methods and apparatus for detecting carbohydrates of interest. The methods and apparatus for synthesizing or detecting carbohydrates involve the use of carbohydrate-modifying enzymes immobilized in a reaction matrix gel and fluorophore labelled substrates that may be removed from the reaction matrix gel by electrophoresis and subsequently analyzed or transferred to another reaction gel matrix. n The subject invention also provides methods for detecting and quantitating specific carbohydrate-modifying enzymes that might be present in a sample for analysis.

标题 :Protein N-glycosylation of eukaryotic cells using dolichol-linked oligosaccharide synthesis pathway, other N-gylosylation-increasing methods, and engineered hosts expressing products with increased N-glycosylation

摘要:The level of glycosylation on products produced by a host (such as CHO cells, HEK cells and other mammalian cells, and non-mammalian cells) or patient can be increased by engineering, such as by supplying the host or patient with a gene sequence. For example, the host or patient can be made to produce desirably glycosylated products by increasing one or both of expression of N-glycan substrate containing lipid-liked oligosaccharide and expression of oligosaccharide (OST) transferase.
