  • 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.

  • Patent number: 8580499
    Abstract: The present invention relates to a method and device for detecting and/or quantifying one or multiple target molecules present in a solution by quantifying online their binding on specific capture molecules immobilized at different locations (spots) of a surface of an optically transparent solid support without substantial detection of target molecules present in solution. The present invention allows multiple target assays to be performed in a simultaneous detection. More particularly, the invention comprises detecting in real-time the hybridization between capture DNA molecules present on a micro-array and target polynucleotides present in solution. The invention is also related to real-time PCR of multiple targets on a micro-array.

  • Patent number: 8288128
    Abstract: The present invention relates to a method and apparatus for monitoring a real-time quantification of multiple target molecules during their binding on capture molecules of a micro-array. The method comprises the steps of: placing, in a chamber (14), a support (15) having fixed upon its surface a micro-array comprising at least 5 capture molecules (20) being immobilized in specifically localized areas (21) of said support; introducing said labeled target molecules solution (13) into the chamber; incubating said labeled target molecules under stable and controlled temperature conditions to allow the binding between said target and capture molecules; directing an excitation light (2) from a light source (1) on the surface of the micro-array; measuring the electromagnetic light emission (7) from the bound target molecules in response to said excitation light in presence of the solution containing the target molecules wherein the surface of emission for a localized area is comprised between about 0.

  • Patent number: 7875442
    Abstract: Disclosed is a system and method conducting real-time PCR. Unlabeled capture molecules of a specific design are immobilized on a solid support, and contacted with amplicons produced in one or more PCR cycles. Detection of amplicons may take place during or between the PCR cycles while the solid support is in fluidic contact with the PCR solution. In an alternate embodiment detection of the amplicons takes place when the solid support is not in fluidic contact with the PCR solution. The method is suitable for the simultaneous detection and quantification of closely homologous target molecules.
