Publication number: 20140024812Abstract: Methods for manipulating carbohydrate processing pathways in cells of interest are provided. Methods are directed at manipulating multiple pathways involved with the sialylation reaction by using recombinant DNA technology and substrate feeding approaches to enable the production of sialylated glycoproteins in cells of interest. These carbohydrate engineering efforts encompass the implementation of new carbohydrate bioassays, the examination of a selection of insect cell lines and the use of bioinformatics to identify gene sequences for critical processing enzymes. The compositions comprise cells of interest producing sialylated glycoproteins. The methods and compositions are useful for heterologous expression of glycoproteins.Type: ApplicationFiled: August 27, 2013Publication date: January 23, 2014Applicants: THE UNIVERSITY OF WYOMING, HUMAN GENOME SCIENCES, INC., THE JOHN HOPKINS UNIVERSITYInventors: Donald JARVIS, Yuan C.

Patent number: 5501841Abstract: A connection type fluid transfer and treatment system apparatus and method for efficiently and continuously executing transfer and treatment of small or micro amounts of sample solutions without substantial transfer loss, which includes a first microsolution reaction microtube having one open end and a second closed end, a second microsolution target microtube having substantially the same shape as the first microtube also having one open end and one closed end, and a connector for connecting together the open ends of the first microtube to the open end of the second tube. The connector includes a foramenous membrane support, which removably receives chemically or biologically treated membranes for applying a predetermined treatment to a solution while passing the sample solution from the first microtube to the second tube. Alternately, a "single use only" connector having disposed therein a membrane pretreated with a quantitative amount of reagent may be used for certain treatment operations.Type: GrantFiled: July 27, 1994Date of Patent: March 26, 1996Assignee: Artchem, Inc.Inventors: Yuan C.
