| Specificity Statement: | This antibody binds PCSK9 and blocks the PCSK9-LDLR interaction in a dose-dependent manner with an IC50 of 2.25±1.23 nM (PMID: 33416098). Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a serine protease enzyme encoded by the PCSK9 gene in humans and it plays a role in regulation of circulating cholesterol. It is associated with autosomal dominant hypercholesterolemia, a state of elevated levels of LDL (low-density lipoprotein) cholesterol. Autosomal dominant hypercholesterolemia can result in severe implications such as stroke and coronary heart disease. |
| Application Notes: | Indirect binding ELISA were performed to assess the specificity of this antibody against PCSK9. Biolayer interferometry analysis suggested that IgG1 version of this antibody had a binding affinity of 1.96±1.56X10−10 M towards PCSK9. In vitro, the PCSK9/low-density lipoprotein receptor (LDLR) pathway of Hep-G2 cells was inhibited by 3D2 treatment, thereby increasing LDL uptake in these cells. In addition, combination treatment with 3D2 and statin was more effective at increasing LDLR levels than treatment with 3D2 or statin alone. Furthermore, in mice treatment with this antibody resulted in a 3-fold increase in hepatic LDLR levels, and lowered total serum cholesterol by up to 61.5% in vivo (PMID: 33416098). |
