Publication number: 20100216969Abstract: The present invention relates generally to methods and carriers for cross-linking or immobilising biomolecules such as polypeptides. In particular, the present invention relates to methods and carriers useful for coupling a polypeptide to a carrier via at least one disulphide bond. The carrier coupled to the biomolecules has applications in the fields of e.g. molecular biology, biochemistry, pharmacology, and medical diagnostic technology.Type: ApplicationFiled: June 27, 2006Publication date: August 26, 2010Applicant: BIONANOPHOTNICS A/SInventors: Torben Snabe, Maria Teresa Neves-Petersen, Steffen Bjorn Petersen

Publication number: 20090222069Abstract: The present invention relates to the field of light induced therapy. The invention relates more particularly to a method of modulating receptor function of cells having receptor proteins, said method comprising illuminating the cells with light in the wavelength interval of 250-305 nm or with light having longer wavelengths that by means of non-linear processes and/or multiphoton excitation promotes the same electronic transitions as light in the wavelength interval of 250-305 nm to modulate said receptor function.Type: ApplicationFiled: November 16, 2006Publication date: September 3, 2009Applicant: Aalborg UniversitetInventors: Steffen Bjorn Petersen, Maria Teresa Neves-Petersen, Olaf-Georg Issinger, Birgitte B. Olsen, Torben Snabe, Soren Klitgaard

Patent number: 6908991Abstract: The present invention relates to mutations of a subtilisin gene which result in changes in the chemical characteristics of subtilisin enzymes. Mutations at specific nucleic acids of the subtilisin gene result in amino acid substitutions and consequently, altered enzyme function. Some of these mutant enzymes exhibit physical properties advantageous to industrial applications, particularly in the detergent industry, providing subtilisin which is more stable to oxidation, possesses greater protease activity, and exhibits improved washability.Type: GrantFiled: December 6, 2002Date of Patent: June 21, 2005Assignee: Novozymes A/SInventors: Sven Hastrup, Sven Branner, Fanny Norris, Steffen Bjorn Petersen, Leif Norskov-Lauridsen, Villy Johannes Jensen, Dorrit Aaslyng

Patent number: 6506589Abstract: The present invention relates to mutations of the subtilisin gene, some of which result in changes in the chemical characteristics of subtilisin enzyme. Mutations are created at specific nucleic acids of the subtilisin gene and, in various specific embodiments, the mutant enzymes possess altered chemical properties including, but not limited to, increased stability to oxidation, augmented proteolytic activity, and improved washability. The present invention also relates, but is not limited to, the amino acid and DNA sequences for two proteases derived from Bacillus lentus variants, subtilisin 147 and subtilisin 309, as well as mutations of these genes and the corresponding mutant enzymes.Type: GrantFiled: June 7, 1995Date of Patent: January 14, 2003Assignee: Novozymes, A/SInventors: Sven Hastrup, Sven Branner, Fanny Norris, Steffen Bjørn Petersen, Leif Nørskov-Lauridsen, Villy Johannes Jensen, Dorrit Aaslyng
