Appl. No.:
12/853759
Inventors:
Pilsoo Kang - Bloomington IN, US
Yehia S. Mechref - Bloomington IN, US
Milos V. Novotny - Bloomington IN, US
Assignee:
Indiana University Research and Technology Corporation - Indianapolis IN
International Classification:
G01N 33/00
C12N 9/26
US Classification:
436 94, 422129, 422 681, 422102, 436 43, 436174, 435201
Abstract:
A solid-phase permethylation procedure is described. For example, solid-phase permethylation can be utilized to prepare permethylated linear and branched, neutral and sialylated oligosaccharides, which can be analyzed by MALDI-MS.

Fluid Treatment Device

View page
US Patent:
20040077101, Apr 22, 2004
Filed:
Oct 18, 2002
Appl. No.:
10/277556
Inventors:
Tony Tegeler - Bloomington IN, US
Yehia Mechref - Bloomington IN, US
Milos Novotny - Bloomington IN, US
International Classification:
G01N001/00
US Classification:
436/174000, 436/173000, 422/099000, 422/100000
Abstract:
A fluid treatment device is disclosed for mixing first and second fluids. The first fluid may be a treatment liquid that is contained in a container and that is used to change a property, such as the pH, density or ionic strength, of the second fluid. In some illustrative embodiments, the fluid treatment device is used to create an effluent by adding a buffer material and/or a matrix material to an analyte for subsequent MALDI MS analysis of the effluent. A mixing space is defined in a container between ends of first and second conduits. In some embodiments, a junction member couples together the ends of the first and second conduits. The junction member has a main passage that receives the ends of the first and second conduits. The junction member has at least one opening that provides fluid communication between an interior region of the container and the mixing space.

Method Of Preparation Of Oligosaccharides

View page
US Patent:
20040096933, May 20, 2004
Filed:
Sep 19, 2003
Appl. No.:
10/664462
Inventors:
Yunping Huang - Urbana IL, US
Tomonori Konse - Hiratsuka-shi, JP
Yehia Mechref - Bloomington IN, US
Milos Novotny - Bloomington IN, US
International Classification:
C12P021/06
C12P019/04
C08B037/00
US Classification:
435/068100, 435/101000, 536/053000
Abstract:
The invention provides a method of cleaving an O-linked oligosaccharide from a glycoprotein. The method comprises the steps of contacting a composition comprising a glycoprotein, wherein the glycoprotein comprises O-linked oligosaccharides, with a solution comprising a borane-ammonia complex to form a mixture comprising the glycoprotein and the borane-ammonia complex, incubating the mixture for a period of time sufficient to cleave the linked oligosaccharides from the glycoprotein, and forming a mixture comprising oligosaccharide alditol products and deglycosylated protein by-products.

435/101000, 536/123000, 536/018700
Abstract:
An ammonium-based -elimination cleavage of linked oligosaccharides from glycoproteins is described. The method enables the isolation of glycoprotein-derived oligosaccharides having a reducing end which enables subsequent derivatization for chromatographic and/or mass spectral analysis. The described glycoprotein cleavage protocol enables structural investigations using low microgram quantities of glycoproteins.
