Patent number: 7825069Abstract: Provided herein are sets of mass labels. Each mass label in a set includes: 1) a mass marker moiety; 2) a mass normalization moiety; and 3) a cleavable linker connecting the mass marker moiety to the mass normalization moiety. Each mass marker moiety is characterized as having a mass different from that of all other mass marker moieties in the set as determined by mass spectrometry. Further, each mass normalization moiety ensures that each mass label in the set has substantially the same mass as determined by mass spectrometry.Type: GrantFiled: August 20, 2007Date of Patent: November 2, 2010Assignee: Electrophoretics LimitedInventors: Gunter Schmidt, Andrew Hugin Thompson, Robert Alexander Walker Johnstone

Patent number: 6702995Abstract: The present invention relates to a delivery system useful for water-insoluble drugs, therapeutic agents, and diagnostic agents. More particularly, it relates to a method of packaging water-insoluble substances such as, for example, a drug or other therapeutic or diagnostic agent, to facilitate uptake into the human or animal body and to substances packaged by this method. The packaging method renders the water-insoluble substance water-soluble by packaging it in an amphiphilic polymer that is soluble in water. The invention also relates to a method of treating cancer through administering a water-insoluble drug or other therapeutic or diagnostic agent packaged according to the method describe above.Type: GrantFiled: June 29, 2000Date of Patent: March 9, 2004Assignee: TheRyte, Ltd.Inventors: Robert Alexander Walker Johnstone, Hilmar Meek Warenius, Thelmo Luis Coutinho Figueiredo, Alexandra Maria Sørensen

Patent number: 6384264Abstract: Organic photoprecursors of amines are provided for use in photosensitive imaging systems, finding particular application in the preparation of lithographic printing plates. Said photoprecursors generate free amines on exposure to long wavelength UV or visible radiation, have high solubility in organic solvents, and include photolabile 2-nitrobenzyl functional groups. Methods for the synthesis of the photoprecursors are described, and the use of the said photoprecursors for the production of printing plates using both positive working and negative working techniques are discussed.Type: GrantFiled: October 18, 2000Date of Patent: May 7, 2002Assignee: Agfa-GevaertInventors: Maria de Lurdes dos Santos Cristiano, John Kynaston Davies, Sharon Dowd, Robert Alexander Walker Johnstone, Michael John Pratt, John Robert Wade

Patent number: 5675042Abstract: Phenols, and related aromatic compounds, phenolic ethers, can be hydroxylated selectively using hydrogen peroxide in the presence of an amorphous or crystalline tin or cerium phosphate catalyst in a solvent containing an aliphatic carboxylic acid. The process is particularly suitable for phenol itself, and advantageously employs a catalyst obtained by heating an hydrated amorphous or crystalline tin or cerium phosphate for example at about 100.degree. C. A convenient hydroxylation temperature is in the range of 50.degree. to 90.degree. C., and a convenient solvent is acetic acid.Type: GrantFiled: August 3, 1995Date of Patent: October 7, 1997Assignee: Solvay Interox LimitedInventor: Robert Alexander Walker Johnstone
