Fusion protein and high-density lipoprotein measurement kit using same

Abstract

A fusion protein being a lipid-free reference standard having good long-term storability, which is used for measuring the quantity or quality of modified HDL, and a method for accurately, repeatability and reliably measuring high-density lipoprotein using the same. In the fusion protein, a complete protein sequence or partial fragment protein sequence for ApoA I is linked directly or via a spacer to a LOX-1 binding protein sequence that binds to a lectin-like oxidized LDL receptor: LOX-1. The method for measuring a modified high-density lipoprotein in a test sample is a method for measuring a modified high-density lipoprotein through binding of the modified high-density lipoprotein to LOX-1 and an anti-APOA I antibody, wherein, using the fusion protein as a reference standard for the modified high-density lipoprotein, the modified high-density lipoprotein in the test sample is determined by comparison with the reference standard through optical detection and/or radiation dosage detection.
