Used in biomedical research to quantify levels of proprotein convertase subtilisin/kexin type 9 (PCSK9) in rat samples. Helps in studying lipid metabolism, particularly LDL cholesterol regulation. Widely applied in preclinical studies for evaluating potential therapies targeting PCSK9, such as inhibitors or gene-based treatments. Enables researchers to assess drug efficacy and understand PCSK9's role in cardiovascular diseases. Suitable for use with serum, plasma, and cell culture supernatants. Provides a reliable, sensitive, and specific measurement for monitoring changes in PCSK9 expression under experimental conditions.
