|Product Overview:||PCSK9 is a crucial player in the regulation of plasma cholesterol homeostasis. It binds to the ectodomain of hepatic low-density lipid receptor family members: low density lipoprotein receptor (LDLR), very low density lipoprotein receptor (VLDLR), apolipoprotein E receptor (LRP1/APOER) and apolipoprotein receptor 2 (LRP8/APOER2), and promotes their degradation. PCSK9 acts via a non-proteolytic mechanism to enhance the degradation of the hepatic LDLR through a clathrin LDLRAP1/ARH-mediated pathway. May prevent the recycling of LDLR from endosomes to the cell surface or direct it to lysosomes for degradation|
|Description:||The PCSK9/LDLR TR-FRET Assay Kit is designed to measure the inhibition of PCSK9 binding to LDLR in a homogeneous 384 reaction format. This FRET-based assay requires no time-consuming washing steps, making it especially suitable for high throughput screening applications. The assay procedure is straightforward and simple; a sample containing europium-labeled (Eu) LDLR ectodomain, dye-labeled acceptor, biotin-labeled PCSK9, and an inhibitor is incubated for two hours. Then, the fluorescence intensity is measured using a fluorescence reader.|
|Applications:||Great for screening small molecular inhibitors for drug discovery and HTS applications.|
|Storage:||At least 6 months from date of receipt when stored as directed.|
