PCSK9 immunoassay

摘要

Methods of using PCSK9 antagonists More specifically, methods for measuring circulating PCSK9 levels in a biological sample by means of an immunoassay The immunoassay used can be a solid phase immunoassay, such as a dissociation-enhanced lanthanide fluorescence immunoassay utilizing an E07 capture antibody or coating and a G08 or H23 detecting antibody.

1. A method of measuring circulating Proprotein Convertase Subtilisin-Kexin 9 (PCSK9) levels in a biological sample obtained from a subject, comprising the steps of performing a solid phase immunoassay on the biological sample to determine a level of PCSK9 therein and comparing the level of PCSK9 in the biological sample against a standard having a known concentration of PCSK9, wherein the immunoassay is performed using a coating or capture antibody that is E07 and a detecting antibody that is H23; and wherein:
a) the E07 antibody comprises a light chain consisting of the amino acid sequence of SEQ ID NO: 3 or 7, and a heavy chain consisting of the amino acid sequence of SEQ ID NO: 4 or 8; and b) the H23 antibody comprises a light chain consisting of the amino acid sequence of SEQ ID NO: 11 or 15, and a heavy chain consisting of the amino acid sequence of SEQ ID NO: 12 or 16.
