Patent number: 7718746Abstract: Anion-binding polymers are described. The anion-binding polymers in some cases are low swelling anion-binding polymers. In some cases, the anion-binding polymers have a pore volume distribution such that a fraction of the polymer is not available for non-interacting solutes above a certain percentage of the MW of the target ion for the polymer. In some cases, the anion-binding polymers are characterized by low ion-binding interference, where the interference is measured in, for example, a gastrointestinal simulant, relative to non-interfering buffer. Pharmaceutical composition, methods of use, and kits are also described.Type: GrantFiled: May 22, 2009Date of Patent: May 18, 2010Assignee: Ilypsa, Inc.Inventors: Eric Connor, Dominique Charmot, Han-Ting Chang, Florence Roger, Gerrit Klaerner, Son Hoai Nguyen, Jonathan Mills, Jerry M.

Publication number: 20030196896Abstract: A method and apparatus are disclosed for screening separation media for performance in capillary electrophoresis. In one aspect the invention comprises concurrently loading a plurality of capillaries from one corresponding end of each with a respective plurality of separation media, adding a sample to each capillary, advancing the samples through the capillaries under an applied electric field, measuring a property of the samples or components thereof as they advance through the capillaries, and using the measured properties to identify one or more preferred sets of separation media. At least one of the steps of loading or advancing are carried out simultaneously over the plurality of capillaries.Type: ApplicationFiled: April 17, 2002Publication date: October 23, 2003Inventors: Thomas Harding McWaid, Oleg Kolosov, Gerrit Klaerner, Miroslav Petro, Son Hoai Nguyen, Sigrid Kuebler

Publication number: 20030172724Abstract: A liquid chromatography column distributor spreads liquid over the internal cross sectional area of the column to facilitate separation of the liquid in the column into its constituent components for analysis, particularly where the volume of liquid is small and the rate of flow through the column is high. The distributor is useful for small volumes, less than 100 micro liters. The distribution is preferably done in two or more stages by two or more plates arranged in series. This arrangement keeps the flow paths short and volumes of channels in the plate carrying the liquid small. The distributor may be used in a high performance liquid chromatography (HPLC) in which liquid flows at high rates through the column. The distributor is constructed to protect the liquid sample from damage.Type: ApplicationFiled: March 15, 2002Publication date: September 18, 2003Applicant: Symyx Technologies, Inc.Inventors: Miroslav Petro, Son Hoai Nguyen
