  • Publication number: 20170175068
    Abstract: The present invention relates to a method for coating a solid support which is suitable for being used in cell culture applications. The method comprises a step in which a solution of a carrier protein, which comprises attached thereto or as a part of its amino acid sequence at least one cell function- modulating peptide sequence, is heated to at least 50° C. and incubated same under conditions which result in the formation of soluble carrier protein aggregates comprising between 2 and 1000 protein molecules. Subsequently, the protein aggregates are brought into contact with the solid support under conditions that allow for the non-covalent adsorption of the aggregates to the support. The invention also relates to a coated solid support having non-covalently adsorbed on its surface at least one of the above-mentioned aggregate of carrier proteins aggregates.

  • Publication number: 20110237455
    Abstract: The invention provides a method and kit for performing the analysis of a microarray surface having immobilized capture molecules used for detection and/or quantification of one or multiple target biological molecules labelled with a fluorophore and being present in a solution comprising a light absorbing agent that has an absorption band which overlaps the emission and/or absorption band of the fluorophore and is not a quencher molecule of the label of the target molecules.

  • Patent number: 7846333
    Abstract: A porous media, a housing containing a porous media and methods for fabricating the housing containing a porous media are provided. The porous media is composed of varying amounts of sorptive binding particles in combination with polymer particles, for example silica particles mixed with polyethylene beads. The porous media is sintered into target housings, for example pipette tips, for use in desalting, purifying and separating biomolecules in target samples. The porous media is also formed into porous media discs via pressure and heating for insertion into housing devices.

  • Patent number: 7153433
    Abstract: Application of a functionalized porous membrane to purify nucleic acids, the binding properties of the membrane with respect to nucleic acids being adjustable by controlling the conditions of an ambient medium. The membrane is functionalized by deprotonated groups.

  • Patent number: 6545144
    Abstract: A method for the isolation of nucleic acids from a liquid sample, which contains nucleic acids, using a filtering device, which has pores, through which the sample is allowed to flow in the course of the isolation, the nucleic acids, and contained in the sample, being retained selectively in or at the pores, wherein the sample is mixed with a concentration of the precipitating agent for nucleic acids, which is sufficient to condense the nucleic acids and the sample is then allowed to flow through the filtering device, the pores of the filtering device used having inner wall regions with variable surface structures, which are constructed differently depending on the medium passed through the pores and by which the permeability of the pores can be adjusted between a state, in which the condensed nucleic acid molecules are retained, and a state, in which the dissolved nucleic acid molecules can pass through.
