|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. 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[Biotinylated]-LDLR Binding Assay Kit is designed for screening and profiling purposes. The key to this kit is the high sensitivity of detection of biotin-labeled PCSK9 by streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, LDLR ectodomain is coated on a 96-well plate. Next, PCSK9 is incubated with LDLR on the plate. Finally, the plate is treated with streptavidin-HRP followed by addition of an HRP substrate to produce chemiluminescence, which can then be measured using a chemiluminescence reader.|
|Applications:||Great for screening small molecules and antibodies that inhibit the binding of PCSK9 to LDLR ectodomain.|
