权利人:BOEHRINGER MANNHEIM GMBH
摘要:For the determination of the rate of nucleic acid synthesis in eukaryotic cells a nucleotide which is non-radioactively labelled or derivatized with a hapten is introduced into the cells with the addition of liposomes and the rate of synthesis of the nucleic acids is determined by means of the incorporation of the nucleotide via its label or derivatization.

标题 :Tuned synthetic dendrimer calibrants for mass spectrometry
发明人：GRAYSON SCOTT
权利人:THE ADMINISTRATORS OF THE TULANE EDUCATIONAL FUND
摘要:Provided are synthetic dendrimer calibrants for mass spectrometry. The calibrants are distinguished by their relative case and rapidity of synthesis, comparatively low cost, long shelf life, high purity, and amenability to batch synthesis as mixtures. The latter characteristic enables parallel preparation of higher molecular weight compounds displaying useful distributions of discrete molecular weights, thereby providing multi-point mass spectrometry calibration standards. Methods of making, tuning and using said calibrants are provided.

发明人：LAROCHE CHRISTOPHE R; PADILLA GERARDO; HALNON TIMOTHY D
权利人:DOW GLOBAL TECHNOLOGIES LLC
摘要:The present invention relates to an aqueous alkanolamine solution for the removal of hydrogen sulfide from gaseous mixtures containing hydrogen sulfide. The aqueous alkanolamine solution comprises (i) an amino compound with the formula:n nR 1 R 2 NCH 2 CH(OH)CH 2 OHn nwherein R 1 and R 2 independently represent lower alkyl groups of 1 to 3 carbon atoms, (ii) piperazine, and (iii) optionally a physical solvent, wherein said solution does not contain a strong acid. Further, the present invention relates to a process for removing hydrogen sulfide from a gaseous mixture containing hydrogen sulfide, and additionally other acid gases, if present, for example carbon dioxide, comprising the step of contacting the gaseous mixture contain hydrogen sulfide with the aqueous alkanolamine solution, preferably wherein the temperature of the aqueous alkanolamine solution is equal to or greater than 140° F. Examples of the gaseous mixtures include natural gas, synthesis gas, tail gas, and refinery gas.
