20100009845 | Pipette Tip Containing Particle-Filled Polymer Monolith - The present invention relates to a pipette tip which is fitted with a porous organic monolith which is doped with active particles. Due to a unique polymerization method, the extraction tips stay highly permeable which allows sample to pass through the monolithic bed. The extraction tip represents an ideal tool for solid phase extraction, especially for desalting, isolating and purifying biomolecules such as peptides and proteins. | 01-14-2010 |
20100078572 | ANALYSIS OF LOW MOLECULAR WEIGHT MOLECULES BY MALDI-MS - The invention relates to a process for the analysis of molecules having a molecular weight of <1500 Da by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), wherein an analyte containing low molecular weight molecules is applied to a matrix material, which is characterized in that the matrix material comprises fullerene-derivatised silica. This process allows clear identification of small molecules through intensive signals without matrix -related background disturbances. | 04-01-2010 |
20100323013 | HYDROLYSATES MADE OF PLANT EXTRACTS AND ANTIBACTERIAL AGENT CONTAINING THE SAME - The present invention relates to an antibacterial agent and a hydrolysate made of at least one extract that has been produced by extraction using ethanol/water from dried plant material of: a) at least one of the plants selected from the group consisting of: | 12-23-2010 |
20120088906 | Isolation of Phosphoproteins, Glycoproteins and Fragments thereof - The invention provides methods and apparatus for the selective isolation of phosphorylated and glycosylated proteins and their fragments. Metal cation is used to precipitate proteins or protein fragments containing phospho groups and/or glyco groups. The sample preparation method can be used for several types of biological samples, including HeLa cells, food, and human cerebrospinal fluid. The proteins are isolated, recovered and ready for analysis by mass spectrometry or other analytical methods allowing detection limits down to the femtomole level. The method and apparatus are valuable tools in the field of protein analysis and diagnostics. | 04-12-2012 |
20120255894 | METHOD FOR COVALENTLY ATTACHING POLYMERIC MONOLITHS TO POLYETHER ETHER KETONE (PEEK) SURFACES - Method for covalently attaching polymeric monoliths to polyether ether ketone (PEEK) surfaces The present invention provides a method of covalently attaching a polymeric monolith to the internal surface of polyether ether ketone (PEEK) tubing and column housings, comprising the steps of: (a) reducing the ketone group of the PEEK to a hydroxyl group to obtain a modified PEEK, (b) optionally reacting the hydroxyl group obtained in step (a) with a compound having an active vinyl group to form a modified PEEK selected from the group of acrylate modified PEEK, methacrylate modified PEEK, styrene modified PEEK and epoxy modified PEEK, and (c) reacting the modified PEEK obtained in step (a) or (b) with a polymer or polymerization mixture for forming the polymeric monolith. Hereby, the mechanical stability and solvent durability of larger diameter monolithic columns as well as their overall performance are improved. | 10-11-2012 |
