Abstract:
A method for determining in silico a set of selected target epitopes suited for the detection of at least one protein of a set of proteins of interest within a pool of sample proteins, comprises the steps of: providing a first list containing the sequences of said sample proteins; providing a second list containing the sequences of said proteins of interest; applying an in silico fragmentation to the sample proteins in said first list to generate a third list containing sequences of possible target peptides having possible target epitopes at their free N- and C-terminal ends, which possible target epitopes each consisting of three to five N- or C-terminal amino acids; generating a fourth list of sequences of valid target peptides by removing from said third list such possible target peptides that are less suited for said protein of interest identification; selecting from said possible target epitopes on said valid target peptides in said fourth list a set of selected target epitopes, said set of selected target epitopes containing at least one target epitope for each protein of interest in said second list, while at the same time containing an as small as possible number of target epitopes.
Abstract:
A method for determining a first physicochemical property of at least two compounds relative to each other uses a second physicochemical property, whereby determination of said first property depends on a third, undetermined physical property, and said first property depends on the composition of the respective compound. Determination of said second property depends on said third property as well, but said second property does not depend on the composition of the respective compound. For each compound a first value for said first property is measured under certain, preferably equilibrium conditions, and simultaneously a second value for said second physical property under said certain conditions is measured. Said first property for each compound relative to the other compound is determined by using said first and second values.

Abstract:
Es wird ein Verfahren zur Durchführung funktioneller Tests an Testzellen mit folgenden Schritten beschrieben: a) Bereitstellen eines Arrays aus voneinander getrennten Messpunkten, an denen jeweils Fängermoleküle immobilisiert sind, an die die Testzellen binden können, b) Erstellen einer Mischung aus den Testzellen und aus Referenzpartikeln, die das Vermögen haben, an die Fängermoleküle zu binden, und die von den Testzellen unterscheidbar sind, c) Kontaktieren der Mischung aus Schritt b) mit dem Array, so dass an jedem Messpunkt Testzellen und Referenzpartikel binden können, und d) Bestimmen des Verhältnisses von interessierenden gebundenen Testzellen zu gebundenen Referenzpartikeln für zumindest einige der Messpunkte. Bei einem weiteren Verfahren ist zumindest ein Messpunkt mit seinen zugeordneten Fängermolekülen auf mehrere Messflächen in dem Array aufgeteilt, die an verschiedenen Stellen im Array angeordnet sind. Das Array wird bei einem anderen Verfahren nach dem Kontaktieren mit den Testzellen und ggf. den Referenzpartikeln bewegt.
Abstract:
A method for determining the concentration/amount of analyte molecules in the sample comprises the step of: (a) adding to the sample a known concentration/amount of competitor or analogue molecules of the analyte, said competitor/analogue molecules being distinct from said analyte molecules, (b) reacting/contacting the sample of step (a) with capture molecules for the analyte and competitor molecules, (c) determining a measure for the ratio R of analyte and competitor molecules that are bound to the capture molecules, (d) determining the concentration/amount of the analyte molecules from the ratio R of step (c) and the known concentration/amount of competitor molecules in the sample of step (a).

The present invention relates to a method and kit for performing assays like immunoassays. The assays are performed by using two different types of magnetic beads.
Abstract:
The present invention relates to a method for the detection and/or enrichment of a large number of different analyte proteins and/or analyte peptides from a sample mixture which includes proteins and/or peptides. The method includes the following steps: a) provision of the sample mixture and, where appropriate, fragmentation of the proteins contained therein into defined peptides, b) provision of first binding molecules which are specific for a peptide epitope of at least one of the various analyte proteins and/or analyte peptides, whereby the peptide epitope includes up to a maximum of five, preferably two to three, amino acids, c) incubation of the first binding molecules with the sample mixture, and d) detection and/or enrichment of the analyte proteins and/or analyte peptides bound to the first binding molecules. The invention also relates to binding molecules which are specific for the terminal peptide epitope of various peptide analytes, whereby the terminal peptide epitope includes the free NH 2 group or the free COOH group, one or more than one amino acid defined by the protease specificity, and in each case up to a maximum of three further terminal amino acids.
Abstract:
Beschrieben wird ein Verfahren zur Herstellung eines Trägers mit einer für die Immobilisierung von Viren geeigneten funktionalisierten Oberfläche und mit auf der funktionalisierten Oberfläche immobilisierten, vorzugsweise infektiösen Viren, sowie die Verwendung von derartigen Trägern. Dabei wird zunächst ein Trägermaterial bereitgestellt und anschliessend zumindest eine Oberfläche des Trägermaterials zur Bildung der funktionalisierten Oberfläche beschichtet, vorzugsweise mit einem Nitrocellulosematerial. In einem nächsten Schritt wird eine Lösung, welche vorzugsweise infektiöse Viren enthält, auf die funktionalisierte Oberfläche aufgebracht, wonach es den Viren anschliessend ermöglicht wird, sich an die funktionalisierte Oberfläche über einen Zeitraum vorzugsweise von 10 Minuten bis 36 Stunden anzuhaften. Die Oberfläche wird danach ggf. mit einem Fluid bedeckt.
Abstract:
The invention relates to a method for producing a carrier provided with a functionalised surface suitable for virus immobilisation and to viruses, preferably infectious viruses which are immobilised on said functionalised surface. The use of said supports is also disclosed. The inventive method consists in preparing a support material, coating at least one surface thereof in such a way that a functionalised surface is formed, preferably with a nitro-cellulose material, in applying a solution containing preferably infectious viruses to the functionalised layer in such a way that the viruses adher thereto, preferably during a period of time ranging from 10 minutes to 36 hours, and possibly in coating said surface with a fluid.
