Title (EN) METHODS OF ASSAYING PROTEINS
(FR) PROCÉDÉS D'ANALYSE DE PROTÉINES
Abstract:
(EN) Methods and systems for identifying a protein within a sample are provided herein. A panel of antibodies are acquired, none of which are specific for a single protein or family of proteins. Additionally, the binding properties of the antibodies in the panel are determined. Further, the protein is iteratively exposed to a panel of antibodies. Additionally, a set of antibodies which bind the protein are determined. The identity of the protein is determined using one or more deconvolution methods based on the known binding properties of the antibodies to match the set of antibodies to a sequence of a protein.
(FR) L'invention concerne des procédés et des systèmes d'identification d'une protéine dans un échantillon. Un panel d'anticorps est acquis, aucun d'entre eux n'étant spécifique à une protéine seule ou à une famille de protéines. De plus, les propriétés de liaison des anticorps dans le panel sont déterminées. En outre, la protéine est exposée de manière itérative à un panel d'anticorps. De plus, un ensemble d'anticorps qui se lient à la protéine est déterminé. L'identité de la protéine est déterminée à l'aide d'un ou de plusieurs procédés de déconvolution reposant sur les propriétés de liaison connues des anticorps pour faire correspondre l'ensemble d'anticorps à une séquence d'une protéine.
