Merck Pcsk9 Elisa

Description: A quantitative ELISA kit for measuring Human in samples from biological fluids.

Description: Proprotein convertase subtilisin kexin 9 (PCSK9), also named neural apoptosis-regulated convertase 1 (NARC-1), is a member of the proteinase K subfamily of subtilisin-related serine endoproteases.  PCSK9 has profound effects on plasma low-density lipoprotein (LDL)-cholesterol (LDL-C) levels through its ability to mediate LDL receptor (LDLR) protein degradation, its primary function. Cell Biolabs? Human PCSK9 ELISA Kit is an enzyme immunoassay developed for the detection and quantitation of human PCSK9 in plasma, serum, cell or tissue lysate samples. Each kit provides sufficient reagents to perform up to 96 assays including standard curve and unknown samples.

Description: Description of target: Crucial player in the regulation of plasma cholesterol homeostasis. Binds to 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 in intracellular acidic compartments. 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. Can induce ubiquitination of LDLR leading to its subsequent degradation. Inhibits intracellular degradation of APOB via the autophagosome/lysosome pathway in a LDLR-independent manner. Involved in the disposal of non-acetylated intermediates of BACE1 in the early secretory pathway. Inhibits epithelial Na+ channel (ENaC)-mediated Na+ absorption by reducing ENaC surface expression primarily by increasing its proteasomal degradation. Regulates neuronal apoptosis via modulation of LRP8/APOER2 levels and related anti-apoptotic signaling pathways.;Species reactivity: Rat;Application: ;Assay info: Assay Methodology: Quantitative Sandwich ELISA;Sensitivity: 0.088 ng/mL

Description: Description of target: PCSK9 is the 9th member of the proprotein convertase family of proteins that activate other proteins.PCSK9 has medical importance because it acts in lipoprotein homeostasis. PCSK9 is ubiquitously expressed in many tissues and cell types. PCSK9 binds to the receptor for low-density lipoprotein particles (LDL), which typically transport 3,000 to 6,000 fat molecules (including cholesterol) per particle, within extracellular fluid. The LDL receptor (LDLR), on liver and other cell membranes, binds and initiates ingestion of LDL-particles from extracellular fluid into cells, thus reducing LDL particle concentrations. ;Species reactivity: Rat;Application: ELISA;Assay info: ;Sensitivity: <10pg/ml
