Used in biomedical research to quantify levels of proprotein convertase subtilisin/kexin type 9 (PCSK9) in mouse samples. Enables researchers to study the role of PCSK9 in lipid metabolism, particularly its impact on low-density lipoprotein (LDL) receptor regulation and cholesterol homeostasis. Commonly applied in preclinical studies evaluating therapeutic agents targeting PCSK9 for the treatment of hypercholesterolemia and cardiovascular diseases. Supports high-throughput screening and validation of drug efficacy in mouse models. Provides a reliable, sensitive, and specific method for measuring PCSK9 concentration in serum, plasma, and cell culture supernatants.
