Patent number: 6294391Abstract: Disclosed is a method of detecting the presence of an analyte of interest in a sample, the method comprising the steps of: providing a binding partner reversibly immobilised on a solid support, said binding partner having binding specificity for the analyte; contacting the sample with the solid support; specifically displacing the binding partner from the solid support in response to the presence of the analyte of interest in the sample, said displacement causing a reduction in the mass of material immobilised on the solid support, thereby generating a detectable change in a mass-dependent property of the solid support; and detecting said change. Also disclosed is an assay device for performing the method of the invention.Type: GrantFiled: May 22, 1997Date of Patent: September 25, 2001Assignee: Unilever Patent Holdings B.V.Inventors: Robert A.

Production of materials rich in conjugated isomers of long chain polyunsaturated fatty acid residues
Patent number: 6271404Abstract: The invention concerns an isomerisation process, wherein materials comprising non-congugated long chain polyunsaturated fatty acids are subjected to base in the presence of an alcohol with ≧3 C-atoms and ≧2 OH groups and having ratio C-atoms: OH-groups of ≧1.25. The resulting reaction product, containing the conjugated isomers is obtained in higher yield at lower temperatures and are not contaminated by presence of non food grade solvent.Type: GrantFiled: July 14, 2000Date of Patent: August 7, 2001Assignee: Unilever Patent Holdings B.V.Inventors: Krish Bhaggan, Frederick William Cain, John Bernard Harris, Victoria Taran -
Patent number: 6255115Abstract: The invention relates to Agrobacterium mediated transformation of moulds comprising species of the fungal sub-divisions Ascomycotina, Basidiomycotina, Deuteromycotina, Mastigomycotina, and Zygomycotina. Examples demonstrate the transformation of Aspergillus awamori (both protoplasts and conidia), Aspergillus nidulans, Aspergillus niger, Colletotrichum gloeosporioides, Fusarium solani pisi, Neurospora crassa, Trichoderma reesei, Pleurotus ostreatus and Agaricus bisporus (all conidia), and Fusarium graminearum (both conidia and rehydrated freeze dried ATCC material). Especially for Aspergillus awamori the transformation frequency is much higher than with conventional mould transformation techniques. It has further been found that not only one expressable gene can be introduced into these moulds, but even multiple copies of such gene, which, moreover, can be targeted e.g. in the chromosomal pyrG locus, as exemplified for A. awamori.Type: GrantFiled: October 7, 1999Date of Patent: July 3, 2001Assignee: Unilever Patent Holdings BVInventors: Alida Godelieve Maria Beijersbergen, Paul Bundock, Robertus Johannes Gouka, Marcellus Johannes Augustinus de Groot, Paul Jan Jacob Hooykaas
